This place couldn't be a more perfect base for a few days in Venice. It is a luxurious place, with marble throughout, very nice and comfortable furnishings, a wonderful kitchen, bathrooms, bedrooms, everything. Perhaps most impt is the location. It is on one of the nicest plazas in Venice, a bit away from the tourist insanity near the city center, both lively and peaceful at the same time (because of its size), with a lot of locals or young tourist congregating in the evenings. Sometimes they got a bit boisterous, but wooden shutters and modern double-paned windows kept the noise to a minimum in the front bedroom. The two other bedrooms were v quiet, and so dark in the AM if you closed the shutters that you could sleep all day (and we almost did for the first two from the US).
It is about an 25 minute walk to St. Mark's square, 20 to the Rialto bridgem and 30 minutes from the farther reaches of the city, but there are many wonderful neighborhoods and attractions closer, if you are not obsessed with the standard tourist sites. Walking Venice is usually the fastest way to go - water buses save energy but rarely time - but walking also means going up and down canal bridges, so be ready. Best advice is to get your 1 or multiday tourist cards for the waterbuses (vaporettos) so you can choose to save your legs on a moment's notice. Local tourist maps are the best at indicating stops and routes.
A hint; put "Pizza Al Volo" into Google maps if you want to be led to the right area. If you put in the name of the square, it will send you to a place about 5-10 mins away. Google maps was critical to getting around.
Barbara was a very pleasant and accommodating host. She met us at the water taxi stop and introduced us to everything, and there was a book of essential facts and recommendations. Like many Venetians, or former ones, she lives on the mainland, about an hour away, so couldn't appear immediately for emergencies, but we didn't have any. All in all, hard to imagine a nicer place to stay in Venice for the price.
