We had a great experience at I Felzi - a perfect location for exploring all of Venezia. The apartment is actually even better and modern than the photos and is located just a 5-10 minute walk from the waterbus from the airport, and also just 10 minutes walking to Rialto. This particular section of Venezia has a bit more character than the southern San Marco section and there are plenty of good restaurants, bars and architecture to frequent.
We were greeted by Roberto's son the moment we arrived via waterbus and he showed us the way around the area and the apartment. Both Roberto and his son were excellent with their communication throughout our stay.
