This place is good for if you need somewhere to sleep, closer to mitte and don't want a hotel. But it is quite impersonal in that is quite clear that the apt is meant as an Airbnb and not somewhere where the host is living normally. It's kind of a shame to see the original concept of Airbnb devolve into something like this, but at the same time I prefer it to a hotel room.
All in all it's a clean and thoughtful place, but the very detailed rules and belittling tone in the accompanying documents imply that there is a significant amount of guests who don't know how to behave.
