It's a mediorce hotel - we moved from Mercure in Wittenbergplatz and preferred Mercure because of the service, staff and location. The staff weren't welcoming, the rooms were large, but the bedding was poor quality, and every time you touched the duvet, feathers came out (my son actually choked on one!). The location is in the business/commercial district and wasn't ideal for us. That said, we were there for the Euros and we were away from all the noise.
