I would definitely stay at Riccardo's apartment again. It was a great value and, only, 30 minutes from Piazzale Roma in Venice. Since my work in Venice is close to Ple. Roma, Riccardo's apartment was great. Riccardo was responsive to my phone call on a weekend. No, Mestre isn't the most exciting city in Italy, but, for a long stay in Venice, it's a great option since there are more supermarkets and normal entertainment options.
