Me and my Fiance had a lovely stay just before Christmas. Berlin was great at that time of year and the hotel was brill. 'Sea-view' was novel and the hotel's style was really cool. Few points; if you do book a sea-view you won't get any day-light and the room gets very warm. Unfortunately the rooms had 2 single beds... More

My mother and I had a wonderful stay here. We checked in on the 17th of December for the Christmas markets and stayed for three nights. The staff were all so friendly and very helpful. We'd booked a Business Class room, for a spot of luxury, but on arrival they advised us that there were no Business Class rooms available,... More

I've never spent so much time fixated on the interior of a hotel. I made sure I got a room facing the aquarium. This was a real treat. Such a fantastic and surreal view from the room!

Wow!! start with the staff, every one of them, from reception through to chambermaids were attentive, polite and charming. Food and beverage was of an extremely high calibre and not unduly expensive for a five star hotel. Our room didn't have much of a view really, but it didn't much matter, the room itself was beautifully clean and well appointed... More
