I stayed in the hotel around 8 to 10 years ago, when I found it nearly perfect. Now I found it perfect again, the room (management suite) was completely clean, modern, comfortable, with a balcony. At other places the bathroom would have a rain-shower in addition to the bathing-tub, which is even more comfortable but not necessary. The team is very friendly and always ready to help. The breakfast is high price but really excellent with a lot of space at the breakfast-table. The aircondition was effective, but I like to switch it of completely for which you need advice from the employees. Close to Potsdamer Platz you have railway, S-Bahn, U-Bahn and bus within 500 m surrounding. I will certainly return.
