We stayed at the hotel for 4 nights in dec 2009/jan 2010. The location is great, in a quiet street, and only a 5 minute walk to a s-bahn station and about 10 minutes to the u-bahn, with a lot of nice restaurants, shops and some grocery stores nearby.
Our room was in the new part of the hotel, which is located just next to the railwaytrack, with trains and metro's running 24 hours a day. All rooms in this part of the building are next to the tracks. We didn't sleep bad because of the trains, but because of a strange loud sound (best described as someone sending morse-codes....) at several times during the night.
The room is quite large and very clean. There's a minibar (with extremely expensive stuff in it, but quite handy for your own Beck's Beers), a quite large flatscreen tv, one normal chair and one relaxing chair and a big bed. The bathroom is quite large as well, with a nice shower, shampoo and bodywash provided (if you like a strong apple-smell). The sink, however, smelled very badly after using it, which was noticed by housekeeping because they closed the discharge the first morning but took no action to fix the problem. We 'fixed' it ourselves by keeping it closed until we went to sleep or left the room, but is was quite horrible. There was no bathtub in the room, and no coffeemakingfacilities, as said in other reviews and like said in other reviews the pillows are tiny. The computers in the lobby were out of service and wireless internet costs 9 euros per hour, which is pretty ridiculous. Breakfast costs about 18 euros, so we skipped it and enjoyed a lot of cheap and nice sandwiches, sausages and other nice stuff at the little kiosks on the street and stations.
While we stayed in the hotel around new year's eve, the costs were pretty high (around 120 euros per night at the 30th and 31st of december, and 'only' 80 euros the night before and after,booked at booking.com, on the hotelwebsite itself it was much more expensive), but this is the case in all of Berlin hotels during this time of the year. However, the party at the Brandenburger Tor was great, and our Savignyplatz s-bahn took us there right away and back without any struggle, how great!
Staff is polite, but we only saw them when we checked in and out, because of the fact guests staying in the new building can use the entrance in the parking garage and do not pass the reception.
Overall, we had a good stay in this hotel, and would recommend it to others, but you should ask for a room in the main building and look for a nice offer on booking.com.
