Lovely flat, it is exactly as pictured. Very clean and comfortable. Worth noting that the building does not have a lift, and the flat is on the third/fourth floor.
Very convenient location. It is indeed up a massive flight of stairs as other guests have noted.
Communications with the host was mostly very good. However, it is worth asking them to confirm everything you have done, as we had a bit of a hiccup:
The accommodation check in form we were asked to fill in was faulty, and information we had filled in did not show up for the host - and we were threatened with legal action (because we had missed a message where he asked us to fill it in a second time). That was scary and caused unnecessarily stress.
So worth checking with them BEFORE you arrive, that they have indeed received all the necessary information to avoid this stress.
