Martina's apartment was really incredible. It was very close to St Marks, a vaporetto stop, and within walking distance to a grocery store. The apartment is right on a canal and during the day, you can hear and see all the gondolas passing through but at night it is very quiet. The apartment had a washing machine with instructions as well as basic kitchen necessities such as coffee and sugar. The cupboard even had a jar of vegemite (a little taste of home for me!)
Enrico greeted us at the vaporetto stop and showed us to the apartment. He gave us a tour and then sat us down with a map and told us his suggestions of where to go and what to eat. We were not able to meet Martina but Enrico was very friendly and helpful. We arrived in Venice prior to our check in time, but Martina and Enrico were very accommodating and allowed us to check in early, for which I am grateful.
I have nothing but good things to say about the whole experience and would highly recommend you stay in this apartment if you are ever in Venice.
