Gio and Roberto have a very nice and very clean home. Their home is only a short 5 minute walk from the Ospedale boat stop (which can be reached on the 5.2 public boat transportation system.) They are very close to a supermarket and restaurants and shops. They are perhaps a 15 minute walk to St Marks Square unless you take a wrong turn which is easy to do in Venice. Finding your way around the narrow walkways and alleys and water canals is part of the challenge and fun of living in Venice. (At least it was for my wife and I)
