This apartment is in a fantastic location both for access to all of central Venice and to the river buses to the other islands and the airport. In this respect it's difficult to over-emphasise the convenience. The host also provided us a wonderful warm welcome, meeting us at the nearest vaporetto stop to show us the way to the apartment and explaining all the necessary details for our stay. She provided a good city map and answered all our questions. She also gave us truly superb restaurant recommendations. For us this was invaluable. We also were given a towels refresh on day 3 of our 7 day stay, which is a nice touch.
The apartment is very quirky, with plenty of unique character. A word of warning though - canal-side location does not necessarily mean always peaceful! If you enjoy rising with the early morning sun, it will probably suit you. If not, the light (some windows have no covering) and the noise from the diesel-powered winch on the barge collecting rubbish daily possibly won't suit you. Nothing, as they say, is perfect, and the apartment is not expensive.
Still, the welcome was terrific, everything is perfectly clean and the bed is extremely comfortable.
