Beatrice's apartment is in a wonderful part of Venice. While it had a lovely calm and local feel, it also had lots of lively and buzzing bars and restaurants further down the street, plus there are three good supermarkets very close by which was great as we were travelling with children and ate in the flat on at least half the evenings.
The transport links are good too - we used the waterbuses a lot (buy a day or three day pass rather than individual journey tickets as much cheaper) The are three stops very close by: Guglie (for airport), Tre Archi and S.Alvise. Plus S.Marcualo/Casino, which is a bit further away but is on more frequent main 'bus' lines and easily walkable to flat, and takes you past a good supermarket (Despar Teatro Italia) which has a ceiling painting like no other supermarket I've been in.
Otherwise the main parts of Venice - certainly the centre - are all within walking distance anyway.
The apartment itself is pretty spacious and well specced out with comfy beds, both of the rooms have their own bathrooms - one of the rooms is very large and has a double bed and the kitchen and dining table in. This wasn't a problem for us as the two children used the other room, but might be more of an issue if you are with another adult couple if they want to use the kitchen before you are up? There is a courtyard outside and it was nice to open the doors in the morning to let the sun while having breakfast. The front garden/courtyard was beautiful with old carvings in stone and fragrant jasmine plants. We loved staying and had a great holiday - we would definitely stay again. David
