Good, perfectly located hotel
We stayed here for a weekend with my wife just to enjoy Berlin atmosphere, food and wine. Generally we were very happy with the balance of the price/quality of Crown Plaza Berlin City Centre.
Cozy room, warm, friendly staff. We did not take breakfast as usually prefer to sleep long during the vacation. SPA area small, clean, and cozy. So far we were in Germany I assumed this is a textile free area, but lot of the visitors were wearing bathing suits while sweating in sauna. It looked a bit strange.
Overall - I will be back.
