Overall, We enjoyed our stay at Andrea's. The location was away from the touristy areas but was still close to everything else.
Initial communication was a little bit frustrating as Andrea was not responsive to texts or email. However, he was extremely responsive to phone calls and was very helpful when we spoke on the phone.
The apartment was very pleasant, it looks exactly the same as the photos, nice and clean. If you haven't been to Venice, you need to prepare yourself for mosquitos but it was kind of Andrea to provide insect repellant.
My only minor criticism is that one of the windows and bathroom door knobs fell off during our stay, and the door lock to our apartment entrance felt a bit loose.
