We had a good experience staying at Cristian's apartment. He was kind to recommend us a local Italian restaurant that served good venetian dishes. While we had a bit of problem finding the apartment, Cristian was waiting for us and helping us to bring in the luggage.
The location of the apartment was good, in between two water terminals, with a short distance away. It was also close to San Giovanni Ospedale which was really a gorgeous building inside.
Overall, we had a good trip and enjoyed the bridges and canals of Venice.
