We had a wonderful stay at Lorenzo's bnb. The room is really nice. Small but very modern, all the fittings are brand new. The location couldn't be better. Lorenzo came to receive us at the water bus stop and his place is just 5-7 minutes from then. The other main sites - San Marco and Rialto-- are not too far either. All the nearby lanes have lots of restaurants. The breakfast served at the Bnb was sufficient too. Lorenzo gives visitors a map of the city with the bnb clearly marked and makes good recommendations for restaurants.
