Valentina's place is in a good location for the value if you've been staying in Venice and have an early flight out of Marco Polo in the morning. Valentina was extremely flexible with our check in time. You can walk from the airport to the airbnb and vice versa. It is truly a 20 minute walk though, not an 11 minute walk, by the time you've reached the actual terminal. Be advised, Valentina's airbnb does have multiple people staying in separate rooms together in the building. Overall, it was a good experience.
