This place is exactly what you would expect. So if you are good with what is listed, you should be fine.
The only thing is these old Venetian houses with old doors do not lock from the inside. Which means the door stay unlocked when you are at home. (Does lock from the outside when you go out).
However there are no turning knobs from the outside, so technically you cannot open door from the outside even if it’s unlocked from the inside
Wanted to mention this in case it bothers you. But I suspect it’s the same for all doors if you want to experience living with the locals and old Venitian houses. Venice is very safe overall and I had no problem staying for a week. :)
