Fabrizio is a great host. Lots of good local tips and very responsive. Apartment location is very quiet and has a secluded feel, but is also super close to the touristy area if that is your thing and also right in the thick of the local scene if that is your thing.
I was here for over two weeks and loved the location. Once you get oriented, it is real easy to get around, either on the streets or the nearby Arsenale vaporetto. Lots of nearby food, services, and a small convenience store that has the basics. For more grocery options you need to go a bit further (10 minutes as opposed to 5), but within very easy distance even if you have two bags of groceries.
Apartment is well stocked for whatever you may want to do. Internet is fast and stable.
Other reviewers mentioned the garbage...I did not have an issue with the recycling and garbage. Information on how to handle was well presented and easy to understand. The collectors come in the morning and knock on the door. They are super friendly and helpful. The drop off location is easy to find with the video Fabrizio provides.
Absolutely perfect for attending the Biennale.
Great spot, would stay again.
