The apartment is in a small hidden ally (as there a thousands in Venice), but close to Campo Santa Maria Formosa and centrally located for an all walking experience in Venice. Some people might be irritated by the surroundings but it appeared to be a very safe area. We were told that the area is a bit less touristy and indeed I feel like you see more locals (especially in the mornings and at night). Venice itself is never the cleanest city, so that’s just something that you have to get used to. It took us longer than advertised to get to the apartment - but we were traveling with a small kid. The apartment is a good size for a group of 4. We were traveling with 5 adults and one kid, and it was still okay. The apartment is well equipped and sealed amenities were provided.
Communication with the host (a professional company) was always prompt and friendly. They do ask you to provide information about all persons staying in the apartment and to pay for the city tax outside of AirBNB (as mentioned in the posting) but it is a legit and trustworthy check-in process. This is because they have to retain that information for the local authorities (law in Italy).
