Stayed at the place with my family of 7 and sharing the experience.
Pros:
1. Very good location, right next to San Marco square.
2. Very good host, helpful and responsive.
Con:
1. Old house and therefore many things are not as comfortable as a modern house.
2. Multiple things in the house were not functional - air conditioner, shower, TV. Ideally, all these should be checked and rectified before checkin guests.
