Flat from ~30 min of tram from main island, with enough commerces / snacks / restaurants / bars open until 1am in neighbor to eat and pass some times there also.
Coming with a car, it was for me a more practical solution with her the free and easy parking, economical, with only few drawbacks. Lot of venitians complains about the airbnbs in the main island who are making the prices too expensives for local people, so was also about that.
Like Nina said, the living room is about a table, dishes and microwave, shared for 3 rooms, but normally if u take are here, it's not to pass your time in the flat but in Venise, so was no problem at all for us.
The bedroom and private bathroom of our room (#3) was confortable and not missing nothing, Nina even provides coffee capsules, shower gel, shampoo, towels, slippers. She speak very well french and perfectly English. I recommend !
