Federica's place was perfect. My partner and I stayed there for 3 nights and were extremely happy. The location was idea--close to San Marco, and tucked away on a smaller, quiet street. The terrace was a huge plus, and made us feel like we were deeply steeped in the neighborhood. The apartment is the size of a medium hotel room (but had all the space we needed), there is a lot of windows and light. Also, Federica is a great host. She was excellent with communication, offered to meet us at the closest boat stop and was flexible enough to meet us at a local square earlier than we had planned. Then she personally escorted us to the apartment, and had recommendations for food and sights. You'll love it.
