Nicola is very fast at responding the messages. We had to delay our meeting time with him because we were stuck in somewhere, and he is very kind. The location is accurate and perfect for us because it is close to the biennale. The only down point I would say is that you cannot pre-drop your luggage in the apartment, so we carried our bags while visiting the biennale. Also, the bath tub is very slippery so be careful. Overall we enjoyed our stay!
