Overall nice place, very clean, modern, nice-looking property, great shower, and we really enjoyed having a balcony and kitchen. Not as comfortable as we hoped though, the whole building has terrible ventilation and the hallways and rooms are hot and stuffy, even on a cool autumn day. Would not want to sleep here on a warm summer day! Also the couch + chairs in our room were comically uncomfortable and the wifi only covered the living room, not the bedroom. I'd probably stay somewhere else next time I'm in Berlin but, if you need a apartment style hotel, this is still a good choice in a nice central location. The staff was very friendly and helpful.
