We - a family with three young kids - spent three fantastic nights at Massimo's place. The house was very spacious, clean and comfortable. The location is incredibly central - in few minutes you can be in San Marco, or get yourself lost in the meanders of this magic town. The public gardens on the East side are also nearby, which was a plus, given that they have playground for the kids. There are also plenty of local shops for food, restaurants, etc.
The highlights were the charming Venetian "campo" the house is on - where kids could roam around freely - and the little terrace where we had the starry sky just for us for romantic dinners.
Communication with Massimo was easy and very good, with plenty of suggestions and recommendations, and check in was straightforward.
I would highly recommend this place!
