This is a lovely and spacious apartment. It is older, well accessoriez and kept in a good condition. Centrally located less than 10 minutes' walk from St. Marco and very close to two vaporetto (motor boats / bus stations).
Caterina and Pierro met us at the Sant'Angelo station and wallsed us to Venice, what a lovely touch.
Make sure to have your navigation skills polished and Google Maps updated or any other app to help you navigate the Venice alleys and to find your way back to the apartment.
Also make sure you know that there's a Venice Occupancy Tax applied on top of your Airbnb charge.
