We had a great stay in this flat. The beds were very comfortable, the view is amazing, especially the one on the roof top :-) Since it's in an old building (200 years old), the rooms are big and very spacious.
We were 5 adults and 3 children, the kids loved to have this space. The flat is clean. The building staircase was a bit too dusty and the entrance hall was not as tidy as in the description pictures. One or two more pots/pans would have been great for the kitchen, since just one pot and one pan was a bit limited.
Deniz was a very helpful host, quick to communicate and a very nice guy. He replaced the kettle that was not working properly. He even found a stroller for us.
I would highly recommend this place for people in search of spaces, top location and who are not too concerned about building tidiness.
