We had a great first time in Venice staying with Leonardo and Irene. We were not able to meet them in person, but Leonardo checked on us throughout our stay. The place is a minute walk from the ferry which will take you to the airport, Murano, Burano, etc. It is also close to a few good restaurants and all major sites in Venice (10-20 minute walk to major attractions). Understandably, as it is summer in Venice, it did get warm in the apartment as it relied on electric fans (no A/C which is pretty typical). We had to get used to this, but overall our stay was wonderful.
