* Communication: virtually non-existent, the host auto-accepted the payment and didn't write a single message to me. The only message she ever wrote to me was the night after we already came.
* Check-in: there was noone to answer the intercom and open the door, even though there was supposed to be according to the instructions. We had to rely on another guest who opened the door to us. Another guest did not have similar problems, though.
* Cleanliness: pretty clean, but quite a lot of dust pretty much everywhere. It wasn't that big of a problem tho.
Other than that, great place, especially for the price I got it for. Just fix the check-in and be more responsive. It's not a nice feeling that even when you're by the door of the appt building in which your accomodation is located, you don't even know if you have a set place to sleep that night. Fix it.
