The location of the apartment is absolutely perfect, only 7 minutes walk from where you arrive in Venice at Piazzale Roma. it is in a lovely relaxed area and provides easy access to all parts of Venice. It only takes 20 mintutes to walk to Piazza San Marco & Doges Palace.
Other information:
We loved Campo Santa Margherita in Dorsoduro region. This is where the nearest good supermarket is and only a 7-8 minute walk from the apartment. It's a nice big square with a good number of relaxed bars and restaurants at a sensible price.
If you want a more expensive eating experience, I can recomment La Patatina di San Giacomo, in San Croce region, about 15 minutes walk.
The bar on the other side of the street from the apartment, was absolutely great, we loved it.
To get the best out Venice, you really need to be prepared to walk.
