Roberto's place is amazing and only 3 minutes walk away from San Marco square. it's really spacious, has everything you need for the stay in Venice. From well equipment kitchen, amazing bathroom, living space, spacious bedroom to air-conditioner which is a must during summer.
You also get a tour guide in the apartment and important informations about Venice. Roberto's very responsible and will help you get around.
Really recommend this place, you won't be disappointed.
