Martina's place is wonderful. She's super kind and helpful, we stayed with our parents and young son, she was very accomodating to us. She lives right near the place, so she personally handled everything (no outsourcing like is often the case now with airbnb).
She was very conscious of us, sending down umbrellas when it rained or offering us a small cot. The house is situated within walking distance from the main Lido Vaporetto stop, with plenty of nice places to eat nearby and extremely friendly people. We had a great stay and highly recommend this place.
