Everything was just fine. The apartment is beautiful, spacious and clean. It's placed in a very good location - you can take a walk from the bus station or train station, or take a vaporetto - the stop is just a few steps from it. There are pubs, bars and restaurants in some close neighbourhood - in my opinion they are better and cheaper than these placed in San Marco (which is pretty close btw, if you take a vaporetto). The host was very kind, helpful and the contact was very good.
I would recommend the apartment to a friend.
