I spent two nights in Marinas apartment with my husband while visiting the Biennale. For us, the location was just perfect: the vaporetto station almost in front of the door, this means in a dead end and so very quiet. Just around the corner is Piazza San Stephano with cafés and restaurants - great for having breakfast.
The apartment was very clean and the bathroom was well equipped with towels, soap and a fan. Even though the bed was little bit short - or my husband is too long =) we slept very well.
Marina is a great and very nice host! Communications with her was very easy and we were happy that she picked us up at the waterbus-station. We can only recommend her place while staying in Venice!
