I stayed at Alessandra's apartment for a long weekend with my sister and mother. This is a great base to explore Venice from. The apartment is cute and homely and was spotlessly clean. The area is peaceful at night and we slept very well. It is well located - only a 5 minute walk from the Academia, a 15 minute walk from San Marco and only 2 minutes from the nearest water bus stop.
Alessandra was a very good host, she was very easy to communicate with and kindly sent us directions to the apartment from the airport. She also let us leave our bags at the apartment on the last day which was great as we had an evening flight.
