We were so happy with our stay at Elena's apartment. The location was so convenient we could just walk anywhere. Elena was great at communicating, showing us how to get to her place very in details, and recommending us places to check out around the area. Since it's in the central of San Marco, it's not quiet during the day but that's when you go out to explore anyway, so that was not an issue for us. We would definitely stay at her place again the next time we travel to Venice.
