We stayed in the Chanel room. We didn't love it, but it was a good location and included a self check-in. Make sure you get the address before you go. The GPS on Airbnb kept bringing us to another street and it took us a while to find the door.
It's a bare bones room, and dated. It's not what we expected for the price we paid. We gave feedback to Valentina, so hopefully it continues to improve for future visitors.
If you're looking for a place to park your stuff when exploring Venice, these apartments will do the trick. Otherwise, it's an underwhelming room in a beautiful city.
