It is a nice studio apartment in a great location. The apartment is tastefully decorated and appropriately sparse. Information about the apartment and Venice is nicely typed up and available on the table when you walk in. It answered almost all our questions. Alberto was great about answering all the other questions, and very promptly. We enjoyed our stay.

One note about staying here and in Venice in general. About 4-5 times a year around full moons or new moons the streets can flood. The apartment is up a level so it is perfectly comfortable. The building is sufficiently high that the ground floor is unaffected in a moderate flood (it was 110cm when we were there), but there were a few inches of water on the walkway in front of the building. It only lasted a few hours around high tide. If you are prepared with plastic over-boots (sold in stores and by street vendors) it is not a big deal. We were surprised the first morning and had to wait it out, but bought the boots that day. However, rolling suitcases around would not be good. We needed to leave for the airport at high tide. Fortunately, there is a dock very close to the door and a water taxi will pick you up (for a price). There are several good apps that will tell you the tide forecast for the next several days to avoid surprises.
