We stayed for 3 nights in Federico's apartment and it was great. We had a private en suite bath, and Federico was very kind to provide a hot pot, coffee, tea and sugar in our room. The apartment is only five minutes' walk from the S. Tomá vaporetto, and his directions on how to get to the apartment were good. Just be careful to get on a vaporetto that is traveling in the right direction! Federico was a great host. His English is very good and he answered all our questions.
