Everything about our stay at Mario's place went off without a single hitch – he immediately answered questions and sent his sister in law to meet us and take us to the apartment, which was spotlessly clean and exactly as described. The neighborhood is one of the most "local" in Venice; not overrun with tourists, but still close to everything (within easy walking distance are San Marco and ... the Venice Biennale, which was why we were there). Easygoing and problem-free, can only recommend.
