The hosts always replied very quickly and friendly (including suggestions where I can find busses etc).
Unfortunately, I had to leave a day earlier and my friend was not able to join me for visa reasons. As I already announced in the very beginning that this might be an issue, I was a bit disappointed that I did not get any refunding (I expected that maybe I get back the little extra money I paid for my friend).
Other then that I was more or less satisfied.
The room looks pretty much as on the pictures, though the other side of the room is a little bit less pretty (but has a little kitchen there).
Although this is announced (so they are fair about this), it is pretty noisy. If you have problems with noise in the night I would not recommend this apartment.
It is super close to many sights by foot, which is great!
