Check in:
Host was away, so the neighbour did the check in & out, both very friendly although they don't speak english at all. SO make sure you contact the host for any question if you don't speak Italian.
We arrived at 23:30pm, the neighbour was waiting us, no extra charge for late checkin. Checked out at 11:30am.

During:
Walking distance to all attractions and boat stops, very quiet location and neighbours.
Very basic sleeping bed and can survive for a few days.

BUT:
There is NO Air conditioner, NO room door, in summer there are so many mosquitos and its very annoying in the night (or you better prepare for it)
You need a lighter if you want to cook, you could get it on the street (cigarette machine)

I would recommend for a group of friends who have a budget and want to live in a town of Venice.

Thanks
