Stayed for 4 days at the beginning of December, we met up with friends at the hotel who had flown in earlier in the day to see the sights and Christmas Markets. The Hotel is well situated to explore the sights of Berlin either on foot or via the excellent S / U Bahn network. The hotel itself is clean and very well run with welcoming, friendly and efficient staff. The rooms are fairly standard and what you would expect of this class of hotel. The only downside with the room was that 1. it had no Tea/coffee making facilities, disappointing as using room service takes an age and is expensive. 2. Our room faced inwards to the lobby area - whilst the view of the fish tank was interesting - there was no natural air and the room was rather stuffy and although the aircon was good makes the atmosphere very dry. The breakfast was substantial with a lot of choices; unfortunately some of the hot choices were less than lukewarm. The Concierge was excellent taking time to assist with enquiries, directions and in booking a restaurant for the Sunday night after a number of abortive attempts or our choice he booked us in at one of his recommendations - 1840 at Hakesher Markt - 10 mins walk from the hotel - an excellent traditional German restaurant - food was wonderful and portions extremely generous !. The only really annoying factor was the lifts - the rooms are laid out in a circular formation around the lobby / fish tank area - there are 4 lifts for some 600 + rooms and NO guest access to the stairs - the stairs are for emergency use only - with a number of malfunctions during our stay leaving only 2 lifts functioning - this lead to many long and frustrating waits to either get up to or down from your room - on one occasion one party called reception after waiting for over 15 mins and were escorted down the stairs to breakfast!. Withstanding the lifts we enjoyed our stay and particularly enjoyed one of the most lively lobby / reception areas we have experienced.
