My wife and I stayed for 2 nites for a weekend getaway and we were really impressed. Staff were very friendly and warm, room was very lovely and extremely clean. Breakfast was awesome - great food and you are spoilt for choice. Close to tube station and to the center of town.Couldnt ask for more. If we ever have to come back to berlin we will definately stay here again.

I stayed in this hotel for more than a week in December for a business trip. The hotel is generally clean. The stuff polite but not too helpful. The room was good size, but not enough storage space and I don't expect too much of it anyway; quiet one, facing internal courtyard, which on the downside meant not too much light. Room service was also decent, but nothing special. All in all an average hotel.

spent 3 nights there in a business trip just before xmass, but with my wife who is interested in the berlin monuments.
as such, i believe it was an excellent and budget-wise choice: the interior is nice, rooms well design-like equipped, and - especially - the staff is extremely attentive but not intrusive which is making the stay a very pleasant experience. location is just brilliant - walking distance to potstdammer, musem insel, topografie des terrors, etc.
breakfast and internet are overpriced (i never understood why in germany, wifi in rooms is not part of the service), but there is plenty places around where you can eat cheap and connect for free. for a dinner, the choice and quality of meals in the hotel restaurant is what you would expect - not cheap, but very tasty.
highly recommended!

Spent 4 nights here in mid December. The exterior is not very exciting but upon entering you will find a very comfortable and welcoming hotel with extremely friendly and efficient staff. The bedroom was very well appointed if a little in need of bathroom tiling repairs. We were at the back of the hotel and there was no noise whatsoever. Breakfast was quite a feast after which we were setup for the day. The location is great, right beside the Anhalter Bahnhof and from there you can get to anywhere in Berlin. Also it's within walking distance of Potsdamer Platz. Will definitely return when we next visit Berlin.
