Nothing much to say. Everything was great. Our host waited for us at the water-bus station to bring us to the apartment which was about 10 min away. Apartment is on the top floor of a very clean and secure building overlooking 2 piazzas, each with a restaurant (Due Colonne's pasta with fish and seafood was absolutely delicious). Apartment is very accessible through water taxis as well which can dock just a few steps from the door.
Martina's sister took the time to prepare a map and show us a few not to miss places (restaurants, gelato, local market, Peggy Guggenheim museum,...)
Only pet peeve is the absence of a living room to relax in once in a while (but as i told the other guests, we are not in Venice to sit around the apartment).
Great stay! thank you!
