Stayed three nights due to exhibition at Excel. Its in walking distance.
Very warm welcome when I reached at 08.00am. Room was ready and I was invited for a complimentary breakfast as well.
Only minus was that I was not able to keep my room until 3.30pm even as a IHG-Club-member. So I had to check-out early morning and leave the luggage with them, which was ok, but would have loved to take a shower in the afternoon and change clothes before returning to the airport and having a night flight...
However, I enjoy the stay, also the train line is just a 2 min walk! [Less]
