Rated 4.5 out of 5 by 124 reviewers.
Rated 1.0 out of 5.0 BAd bad bad I was given my room key upon check in... Early I might add, as a priority club member. When I got to the too. And opened the door, there were already people in the room, that had not even checked out yet. The man was coming out of shower in a towel. I wen down to front desk and told them what happened and they have me a new room. However, the new room was 2 grades lower than what I originally was given, and was offered no upgrades, no discounts or refunds, nothing at all. Not even free meal... I am very unhappy!

Rated 4.0 out of 5.0 by Great, except for breakfast Chose this property because of location- From this hotel I was able to access entire LA/Orange area with ease. Room was comfortable , what you would expect in a Holiday Inn. My issue was Breakfast- on every morning large tour group would descend on breakfast buffet pushing, shoving, inconsiderate,and totally lacking of any consideration of anyone else, or the concept of a "line", or que. They took piles of fruit, boxed cereal & anything else that would travel- obviously for consumption later in the day- most certainly NOT for eating at the table for breakfast. The buffet line looked as if attackjed by locusts when at last they were gone. I attempted to mae a waffle- but batter stuck to waffle iron twice- Thank goodness the staff was alert enough to see my plight & offered to ahve kitchen make a waffle for me. Whoever does group sales at this facility should have booked seperate breakfast arrangements for that tour group, rather than subject other guests to that. September 4, 2013
Rated 4.0 out of 5.0 by Fresh, clean hotel Pleanty of room lighting, good WiFi. A nicer desk could be provided. Visibility of the TV from the work serface could be better. August 31, 2013
Rated 5.0 out of 5.0 by Comfort at its best!!!! We came from out of town not knowing what kind of hotels we would find but we were so lucky to find this one. The check in was great. When we got thier everyone greeted us with a hello. The front desk agent (the one with glasses) was very helpfull and recommended some good restaurants in the local area.The hotel room was clean and spacious. Over all our night was very peaceful and perfect. I would definitely stay at this hotel again. August 27, 2013
Rated 3.0 out of 5.0 by Excellent facility but poor customer service We originally booked only for one night but since the rooms are nice and clean plus comfortable beds so we decided to extend our stay for one more night. I ask several times and spoke to rep Diego if theres anything that I have to do maybe perhaps sign papers but he said no....We are surprise after enjoying our day out and come back to our room but our key didnt work at all, no one bothered letting us know that we have to reactivate it. Also, I had requested to fix the refrigerator in the room several times but still we checked out the was still broken. All I can say it would have been perfect wedding anniversary for us!!!!!

Rated 5.0 out of 5.0 by thanks for the up-grade, great room Enjoyed the stay..Great staff, personal and friendly. July 25, 2013
Rated 4.0 out of 5.0 by Almost Great This location continues to improve and provide a great all-around service. The only thing that remains for an upgrade is room decor (wallpaper, etc.). It seems like that is the last thing on the list of renovations to catch up to the other Holiday Inn Express locations that have fully refreshed their interiors. One of the best steak and egg breakfasts I've ever had. Double-pane windows on the freeway side are also necessary. I slept at a Holiday Inn Express in Old-Town the night before and although it was only feet from a busy freeway, the double-pane windows meant that I couldn't hear a sound - this location would benefit greatly from the same.

Rated 5.0 out of 5.0 by One of the Best HIs I have ever stayed at EVERYONE was friendly and helpful. One of the best HIs I have every stayed at. EXCELLENT value! Full buffet breakfast each morning for PC members. Will definitely stay here whenever I am in the area. July 4, 2013
Rated 4.0 out of 5.0 by Holiday Inn Diamond Bar A very nice full service hotel with upgraded amenities. Even though the hotel was full, the staff was attentive and personal. The staff was very accommodating and helpful. The room was comfortable. The HVAC was a bit noisy but tolerable. Co.mplementary WiFi worked well June 22, 2013
Rated 5.0 out of 5.0 by Great people, clean rooms, confortable bed. Great people, have stayed here several times, the staff is always very nice. One of the best Holiday Inns I have stayed at. I always try to stay at Holiday Inn because they have a great reward program. June 19, 2013

Rated 5.0 out of 5.0 by Worked for me One of my favorite hotels to stay when travelling to Southern California. Located in middle between Los Angeles, Inland Empire, and Orange County. Typically choose this hotel when I need to shuttle between offices in these locations. Fitness room and breakfast are better than average Holiday Inn. Cumbersome to drive from here to LA, but Metrolink Train is only 5 minute drive or 20 minute walk from hotel. Plan on over hour drive to LA or Orange County furing rush hour. June 2, 2013

Rated 4.0 out of 5.0 by Gov employee The rooms were very clean and bed are comfy, although they needed to train there receptionist better, I have to go back and ask for my breakfast coupon cause she didnt give me any, and also she didnt even greeted me as a priority member.. I guest Im to low on the pool. the day I check out never check the name on my receipt so when I get to my office the next day I checked my receipt so that I can turn it in for my travel, they give me a wrong reciept!! it was some one else name on the receit !! so I called back to the hotel and the receptionis put me on hold for 15 minutes or more OMG, so I hang up again and called back, then I get a nice lady on the phone and she fixed everything, her name is Kimberly lu thanks Kim you done a good job keep up the good work I will see you next month I decided to come back on that hotel just because you provided me a good serviced. Keep up the good work Kim.. The resturant also served very nice food... and a good breakfast....with my coupon lol..... May 22, 2013

Rated 5.0 out of 5.0 by May 1st Stay When travelling to the area for work, I always stay at the Diamond Bar Holiday Inn.

Rated 5.0 out of 5.0 by Breakfast I enjoyed my stay and the staff at breakfast were superb! April 24, 2013
Rated 5.0 out of 5.0 by Comfortable bed, excellent food & service. I had made arrangements through the reservations line for a room for my husband and 3 grandchildren. The agent was very nice and knowledgeable when asking about our trip and travel necessities. The room was clean and the beds were very comfortable. The food at their buffet was excellent as well as their staff service. We will definitely go back again next time we're in California. April 22, 2013
Rated 5.0 out of 5.0 by Great service for business travel Room is not big, but it is clean and well equipped. Internet is fast and room is very quiet for business traveler. Breakfast is full of choice and complementary. April 16, 2013
Rated 5.0 out of 5.0 by Nice hotel Nice hotel, good location, and friendly staff. Good value for the area. One note of caution, if noise bothers you, make sure you ask for a room on the hillside and not the freeway side. Decent restaurant/bar on property. Would definitely stay here again. April 8, 2013
Rated 4.0 out of 5.0 by Fast check in Have stayed at the hotel several times, the fast check in always impresses me. April 2, 2013
Rated 5.0 out of 5.0 by Comfortable bed, great value Diamond Bar HIE ranks higher than most others. Helpful staff, comfortable room, ease of parking are a couple highlights. Breakfast buffett was fresh and plentyfull, evidently part of the room package if you chose that rate, as staff seemed perplexed when we didn't have a coupon. Oh well, we didn't see that option and not a deal breaker either way with the "kid" eating free which was nice. Overall a pleasant experience and would recommend this hotel if staying in the area.
