Localisation is great and the owner responds really fast. During our visit he was in another country, however there is another housekeeper, who provided us with things we needed. Just keep in mind the time difference trying to reach the owner.
We loved our stay. Haven't noticed anything problematic. Reaching 6th floor isn't that bad, especially when there is such a lovely view from window. Using a toilet placed outside the room wasn't a problem for us. It's on the same floor.
It's a cozy place for tourists' needs.
