This is not an airbnb apartment and also not exactly an apartment hotel, even though it's defined as one. It resembles much more to a regular basic hotel. The apartment you get is basically a hotel room, and not a big one. It doesn't feel like an apartment. However, it looks fresh and nice, with modern design. There's an Nespresso machine. A cleaning service arrives once a week.
The location is OK. Not very central but with good Tram and S-Bahn lines that will take you quickly to main areas like Alexanderplatz and Hacksher Market. Not a lot to do around the place itself.
Service is courteous but I was quite surprised to find out that they do not provide soap for the bathroom's sink, only body soap for the shower. I never had an airbnb or a hotel not providing sink-soap and it seems completely elementary. The front desk's people didn't seem to think that.
All in all, it's a good value for money and it answers most needs, at least if they are basic.
