My mother and I stayed in Venice for two nights in March. We were originally going to be arriving late and he was very accommodating with this, but our plans changed and we tried contacting him various times with no response. So we ventured Venice with our luggage. He finally responded more then five hours later.
When we took the boat to the address he gave us, we could not find the house and tried messaging him and calling him for at least 30 minutes before he answered the phone and found us. Once he did find us, he could sense our frustration but was very nice and led us to his house.
Once in the house, we noticed that the house smelled like smoke everywhere. My mom and I are sure that the people living in the house smoke inside and even though the room we stayed in was upstairs, it still smelled a lot everywhere.
None of the doors except the front door had locks on it which I did not think would bother me but with the combination of the smoke, it did a lot.
Also, the wifi only worked if you were no more than 3 or so feet from the router.
