A very unusual hotel. Next to the Berlin Wall and a recording studio. There are a lot of musicians in the hotel. There are concerts in the evenings. The breakfasts are excellent. I found the room all pink, and I was pulling my eyes... But it's not critical, it's cool!
Nice hotel. The disadvantages are very high prices and some rooms are highly overrated.
One of the advantages is parties every day with invited musicians. The area is very nice, close to the legendary Berlin clubs and the Kreuzberg district.
