Sergio's place is very clean and looks exactly like how it is depicted in the photos. He is a great host and responds promptly. Our neighbor upstairs is also very friendly and helped us with things we were unfamiliar with around the house.
The A/C worked well but did not circulate throughout all the rooms at night. The machine could only be put on low fan mode due to the noise it made which disturbed us and other residents. Also we had an issue with hot water sporadically turning off. Although it was a quick fix, it was a little annoying to have to deal with but Sergio told us he would look into it.
Aside from these inconveniences, we had a great stay in Venice. The Airbnb was comforting to return to and is located in an area where locals stay so the neighborhood was filled with great options for food. There is a bar down the block where we frequented, affordable authentic Italian cuisine not too far away, and is walkable distance from major tourist attractions. However, if you would rather not walk, there are several vaporetto (water bus) stops not more than a ten minute walk away.
