We stayed in Venice for four nights, and Andrea & Isabella were excellent hosts. Andrea met us at the waterbus stop and carried our bag for us to the apartment.
Communication was superb, they were in contact within minutes of the reservation and pro-actively suggested ways to get to the apartment and things to do in the city. Andrea and Isabella were always extremely friendly and welcoming and we felt like valued guests.
The apartment was exactly as it appears in the photos. It is huge for 2 people with everything you'd need for your stay (even a kettle!). There is also wardrobe space for your clothes (not always the case with AirBnB).
Location is excellent, away from the crowds of San Marco but only a 15 minute walk. Everywhere is walkable within 30 minutes, but most places are a 15 minute walk. We enjoyed watching the cruise ships sailing past the window (this wasn't noisy or intrusive) and the storms closing in were spectacular! Some great views across the water.
We would definitely recommend this apartment and will definitely stay again.
