We were very satisfied with our stay in Cristian's flat. He was responsive to all of our concerns. The flat was clean with plenty of space and in a great location. The only inconvenience was that the building was situated directly above some bars that played loud music late into the evenings, so I wouldn't recommend this for someone who is a light sleeper. There seem to be several airbnb flats in the same building, so make sure you are with the correct host when checking in (a different host mistook us for her guests when we first arrived, and we were almost placed in the wrong apartment).
