Loved Roberto's apartment. Modern facilities along side antiques. Very clean and with everything that you will need for a comfortable stay in Venice. There are several very good restaurants in the area. Plan on being lost a lot, not because of the location of Roberto's apartment but because you are in Venice. Not sure who was lost more; me or google maps.
Roberto's apartment is perfectly located for arrival or departure to/from Venice. If you are traveling with luggage you don't want to drag it around Venice. We arrived by train and departed by plane. It is 20 minutes from the train station to Fondamente Nuove where you will be met by a family member and then a short walk to the apartment. It is 40 minutes from Fondamente Nuove to the airport. Of course all of this is by boat.
If we ever return to Venice, and I will, we would hope to stay in Roberto's apartment.
