The flat looks just like on the photos. The building itself seems old, but it's clean inside and there are clearly people living in it. The grocery store on the ground floor is very convenient and makes it feel safer (it's open until 22 on most days). The streets in the neighbourhood are somewhat empty though, especially later in the evening.
There's no personal contact with the host.
The only issues for us were that we found a little spot of mold in the bedroom under the radiator and the selection of shampoos in the bathroom seemed more like leftovers, with some bottles almost empty (although definitely usable).
Overall a nice experience and the host responds very quickly.
