Staying at Hesen's appartment was by far not our best AirBnb experience. In fact, it wasn't a real AirBnb experience at all because from the first moment on you could see that nobody was living in that building. It wasn't cozy at all, there was nothing except an empty kitchen and bathroom, the sofa and the two empty rooms with just the bunk beds.
There wasn't even salt for example - but Hesen didn't tick the "Essentials" in his ad, so that's okay. You just have to be prepared.
Also, we think that paying a cleaning fee is pretty ridiculous, because nothing was cleaned properly anyways. There where leftovers from the ones who stayed there the week before (I hope so..), hair in the showers and the floor was dusty. The beds, in defense for Hesen, were fine and comfortable.
Furthermore the wifi is NOT working. We read the last recommendations saying that it doesn't work so we asked Hesen when we arrived: He said it does work fine, so either he was lying or not checking his reviews on AirBnb.
The oven didn't work (the stove did) and we were not able to turn on the TV. Maybe it did work and it was us but yeah, nobody showed us how to do it anyways.
Hesen was punctual, he answered quickly (except one telephone call) but just gave us the keys without further instructions or nice words about his city. I was happy that I already lived there for some time years ago, because we could've got lost otherwise.
Walking distance to the station is 7-10 minutes, into the city like 20-25 minutes, so that's true.

Summarized, it's an okay place to stay in for young people a few days because it's equally cheap as an hostel I guess and you have the whole house for you. But if you want a cozy, nice AirBnb experience in the beloved flat from somebody else, that's not your appartment.
