We stayed in Holiday Inn Express Amsterdam Arena Towers for a couple of nights this July, and we really enjoyed the spacious rooms provided. They were much bigger than the rooms from other Holiday Inn Express hotels across Europe. Also notice that the hotel is a part of a brand new building complex. Although it's a far away from central Amsterdam, you can reach the city's centre in a few minutes by metro (metro stops about 800m far from the hotel). Breakfast was better than average 3 star hotel's one. Everyone there was really helpful an prompt. We strongly recoment that hotel for anyone who is looking for a not central hotel. Note also that is biside Amsterdam Arena, where AJAX plays.
