few years ago we stayed in the san polo area in a studio apartment. we loved the area and the place. owned by a lovely couple, ketti and pietro, it is behind frari church.
cabadoer-venice-flat.it: we stayed in the west studio, small kitchenette, washer, small balcony, living area with bed, bathroom/shower, small elevator, luggage storage. we arrived by water taxi to san toma stop and walked to apartment. if interested, fill out form and submit or email them and they are great at getting back.
la levantina: loved this ground apartment on a canal, behind a gate, terrace outside, open dining area and see gondolas and boats going by. email them for availability or check on booking.com scroll and contact host
cross-pollinate.com: has some apartments around the island, look at map, read fine print. if mobility issues check what floor and how many steps/stairs to climb with luggage.
booking.com: filter to apartments (gondola verde veniceiloveyou) (rialto apartments) (charming venice apartments with terrace) just a few to check out. i think you'll be happy in an apartment. more room, kitchen, washer, we always look for a terrace/balcony for coffee hour or happy hour. you don't have to cook, it is nice to have fridge for cold things, snacks. some rooms are smaller than here in states, stars meant different things (amenities) than the states, make sure so shared bath, arrival times and departures too early can't check in, early flight is what is transportation to airport.
read up europeforvisitors,com lots of info there, any other questions just ask, we want you to have great vacation, no stress.
if you are interested i'll message you of things you can do around the area, lots to do. have fun
the island is small to walk around, get "lost", zig instead of zag. i love this magical place, been 3 times. some places may
