We really enjoyed our stay at Adriano's apartment. The apartment is really well equipped and has everything you would need for a self catering stay.
The apartment is ideally located for all of the main sights in Venice which are all within half and hours walk. We didn't need to use the water buses to get around, only on one day when we went to the surrounding islands.
Getting to and from the airport is easy by boat using the Orange Line.
There are some cheap (by Venice standards) restaurants near by. Muro San Stae was good value and only two minutes away. Bar Rosa, about 10 minutes walk, was very cheap. Trattoria Alla Ferrata (a few meters from Bar Rosa) is very well priced and the food is brilliant. Can also recommend Al Nono Risorto, though worth booking a table as it got very busy.
The train station is only 12 mins walk away if you want to travel further afield, we spent one day in Verona.
