I stayed in a double room with my boyfriend, the location is perfect, just a few minutes from Berghain and bars and restaurants were close. Staff was super friendly and we got everything we needed. Rooms, toilets and showers were clean. There is
free parking but its a few hundred meters away and there are not always free spots available, but if dont arrive too late you should be able to get a spot. All in all everything was perfect for a weekend Berlin trip! :)
