This apartment is a perfect home base from which to explore the wonders of Venice, especially if you want to be in a real residential area away from the crowds. We loved having all the different balconies and windows with views overlooking both a placid, classic canal and the back-courtyard space of several residential buildings. There seemed to be enough balconies that I would sometimes forget which was which and where they all were!
Larger canals are just a couple minutes' walk, with restaurants and shops. At the end of our 4-night stay, we all agreed that the location was great because we saw more of the "true," calm Venice and less of the crazy touristy areas. For getting to and from the airport, you are only about a 2- or 3-minute walk from the location where the Alilaguna boat stops. The train station is not far away either.
The apartment itself is comfortable and spacious, with a kitchen/dining area, a separate sitting room, and by far the largest sink of any bathroom I have ever seen in my life (and a rain shower). There is air conditioning in the kitchen/dining area and the main bedroom, which was plenty for us.
The apartment is in an extremely quiet area with pretty much zero foot or boat traffic, so if you're looking for quiet and calm, this is the place to be.
Carmen was extremely responsive, very helpful, and very concerned that everything was perfect for our stay. She provided a large amount of written information about the apartment, far more than we got from any other Airbnb host on our 3-week Europe trip. The wi-fi was fast and worked great.
