This was an excellant hotel in terms of the room, breakfast and location.
Room - We stayed in a triple standard room which was actually on two floors with a spiral stair case leading from one room to the other. This gave a nice spacious feel. Clean, comfortable and modern.
Breakfast - This was first class and went beyond the usual continental arrangement. There were cold meats, rolls, cheeses, etc, however in addition there were hot foods including scrambled egg, sausages, bacon, etc all included in our B&B room rate.
Location - Attractive location on Spree River, about 20-25 mins walk from the Brandenburg Gate, Reichstag. Very nice local retsaurant/bar, Paulaner's im Spreebogen, just along from the hotel, 10-12 euro's for main course in large portions.

There are many good things you can tell about this hotel, but the choice of breakfast exceeds any 5* hotel I've been to. You must try it before you can believe your eyes. The price is reasonable, especially for groups and pre-booked business travel. The location isn't all that central, but it's well linked by public transport and not far from Tegel airport (taxi about EUR12). The rooms are spacious and most of them fully equipped and furnished. Some don't have a proper shower, but a curtained bathroom area, like in Holland. It's great for joggers, as there's a lovely train running by the hotel. It's peaceful and quiet and the Spree river provides some nice views, especially at sunset. The staff is helpful and generally no problems whatsoever. But their breakfast...!

i stayed here for a business conference. staff was friendly and helpful, conference facilities were perfect. also a stunning view from the gym.

We were two couples, staying in August 2011. We booked the hotel at the hotel web site (89 eur). The price was the same as any other sites, but we got a bonus - you can pick from a 'special coffee' or a sparkling wine. We went for wine and drank it in the evening at the hotel bar. It is a very 'warm', pleasant bar, great service, we got all kinds of nuts with the wine as well. It has a nice atmosphere, you feel like coming home from a day of sightseeing.
I think that the hotel is advertised as a business hotel, but I believe that it is great for any purpose. There is also fitness and sauna which we didn't try and we had a view of the river even though we did not book it.
The room and the bathroom were perfectly clean, very comfortable - 4 stars level, spacious and with everything you expect to have in your hotel room.
The location is fine, not right in the center (unter den linden), but not too far either. 10 minutes by bus to the brandenburger tor/unter den linden and 5 minutes from the main railway station (hauptbanhof). The bus stop is right next to the hotel.
We did not take the breakfast at the hotel but had a coffee with cakes in a coffee place which is basically in the same building as the hotel. There is also a supermarket and a bistro next door.
reasonable price (value for money), good location, great service, very nice rooms and interior. recommended!
