Just had a wonderful stay in this great hptel. recently renovated, it is quite a modern hotel anyway and surprised that they spent so much money on upgrading the lobby, bars, and the exec lounge (which is one of the nicest i have been in). The rooms are same but there was nothing wrong with them so very happy with them as they are. Lovely pool and seperate mens and ladies saunas in the locker rooms and a nice gym. Have stayed here many time before and the staff are nice and friendly. Great location on Potsdamer Platz. Also recently stayed at the Ritz Carlton just next door which is also lovely if you feel like splashing out a bit, but the Marriott is great!
