We had a great time staying in Caterina's quaint AirBnb! Caterina herself lives in the apartment right next door so check-in was very easy and she was able to meet us even though our train was delayed. While not necessarily located in the heart of Venice, this true Venetian stay is very close (5 min walk) to the train and water bus station. San Marco square is very accessible by walking (20 min walk). The neighborhood itself is very lovely with few tourists and plenty of beautiful bridges and canals to enjoy.
