I stayed 4 days as part of a conference.
I was impressed by the level of professionalism, politeness, and constant availability of the staff as well as the high quality of the infrastructure, hotel
rooms and restaurant services. I would definitely recommend it for conferences and meetings and business travelers in general.
Rooms are really spaceous, very clean and comfortable and with a modern feel.
Breakfast is hearty and with healthy, "rich", asian, and local menu options and lunch and dinner were definitely above the expected quality for "standard hotel food".
The lobby bar has a reasonably wide choice of drinks available, but the staff can be overwhelmed during busy hours and service could be a little slow at times. Non-smokers should be warned that in Serbia smoking is allowed in bars and restaurants so be prepared to face cigarette smoke around you while enjoying a drink at the lobby bar.
The free internet provided was uninterrupted and of adequate speed that you can stream content from your favourite web TV channel or app reasonably well.
I did not have the time to visit the spa or fitness center, but definitely next time. [Less]
