We stayed at Casa Scarpa with a group of friends for a month and had a wonderful time. The house is located in an area called Dorsoduro that might seem a bit far when you look in googlemaps, but it is definitely the place to be in Venice. Dorsoduro is not only off the crowded touristy area near San Marco, San Polo, etc, but also you can wonder around some of the nicest canal areas of Venice. If you want to hang out Campo Santa Margherita is 5 minutes walking. The house is around the corner of San Basilio waterstop, which made it very convenient for moving with luggage (no bridges!). Plus, Accademia, Alilaguna ferry from Marco Polo airport and Zattere are five minutes walking. So, either if you want to walk or take the vaporetto the location is ideal.
The house has three bedrooms, a beautiful garden and a studio that overlooks both canals. A supermarket that closes at 11pm is around the corner, and there is a grocery store one block from the house. Mirko and Carlotta are great hosts and were always ready to help us with whatever we needed.
