SUCH a beautiful place. The building is gorgeous with unique views of the Grand Canal. Like most buildings on the island, it is many hundreds of years old so you will have to carry your luggage up a few flights of stairs. Wasn't a problem for us, but I just wanted to mention that. Caterina had printed out an extremely helpful guide to Venice, which was very nice to reference whenever we didn't have anything planned. She was a wonderful host and I feel like we got the best place we could've possibly found, especially for the price.
Side note: AirBnb was having server issues and our messages weren't going through for over an hour while we were trying to check in, so I would recommend exchanging whats app information with Caterina/Pietro before you arrive in Venice so that you have an alternative mode of contact.
We'll definitely be back!
