Patrizia's apartment is a great find: near a main route through Venice, but nice and quiet due to being down a little side alley.
The flat is both cleverly and stylishly designed, fitting a nice kitchen, bathroom and bedroom into a fairly small space. The interior looks great, with a combination of minimalist colours and vintage touches like line-drawings of Roman monuments and an antique-looking chandelier.
It has aircon, which you really in need in Venice in summer, and the bed is really comfortable, so you'll get a good night's sleep. The one drawback here was a small window next to the bed, which looks great but has no cover/curtain, so at night it can be bright. I piled cushions up against the window and that worked well.
The area (Cannareggio) is awesome. Apparently it's one of the more Venetian areas in the city, so there are lots of great local places to go. Patrizia can give you great tips.
All in all, I'd strongly recommend this place.
