Concerning the place, the apartment is spacious, correctly located and newly renovated. Unfortunately the bed is very smooth and uncomfortable. As you are walking a lot in Venezia, it's really a pain...
Concerning the host, I don't have much good things to say. The service is really not worth the price. At our arrival, nobody to welcome us in any easy reachable place. The host was waiting closed up in the apartment which is in a very small backstreet, she was there without any cellphone, impossible to reach her... So we had to call Pietro several times (on our cost) to arrive there finally after walking more than one hour in the heat, the busy streets and with the luggages! "Welcome to Venezia!"
Then the same day at night time 9pm, global PowerCut in the apartment as the electrical system was not well installed ! It took them 13 hours, one evening and one morning to intervene... while we had to wait for them, stressed, in the apartment without electricity... "Magical Venezia!"...
Then they fixed it but the second night, again, PowerCut !! We fixed it ourselves unplugging the fridge and dishwasher as we didn't want to ruin half day again waiting for hypothetical electricians all trip long. So it stressed us up, and ruined the magic, we lost the food we bought which was in the fridge and had to go to restaurants much more than expected (and they are expensive in Venezia).
We asked for one night pay back as it would have been accepted everywhere in any respectful hotel. But Pietro refused, he answered us in Italian (while he knew we couldn't speak italian !! Shame on him !!) and plus he complained about us not calling them again (we didn't come to Venezia to fix the electrical system of our host !) and that we let some dirty dishes (while the dishwasher wasn't working because of him ! plus we payed for cleaning lady!...). Really not professional and super upsetting behavior... At the end, just to calm us down, not recognizing his faults, he proposed a "symbolical" 50e payback which shows he really couldn't see the situation from the client's point of view... For us, he runs his 9 apartments as a very profitable business, but not at all in the spirit of Airbnb...
Following our bad experience, we really don't advice you to reserve to this host, it's unsafe. They are many great options for that price in Venezia.
Have a good trip in that beautiful city.
