We have spent 4 days in Venice with the whole family. The apartment is in a fantastic location in a quiet and beatiful neighborhood but near the vaporetto station. Federico was very kind. He was waiting for us when we arrived to Venice and accompanied us to the apartment. He showed us the apt. and then he gave us some good advice about what to do and what to avoid when visiting the town, including good restaurants.
In conclusion, it has been a very good experience and we strongly recommend Federico's apartment.
