We really enjoyed our experience at Leonardo's place. Although we sadly never got to meet him in person, his instructions for finding the unit and picking up the keys were perfect. We ran into no problems while we were there and everything worked as we expected, including WiFi and plenty of hot water. Although it was very hot in Venice during our stay and there is no air conditioning, we found the bedroom fan to be adequate and kept us cool enough.
We particularly enjoyed his location, removed from the craziness of touristy Venice. Sure, we could still get to San Marcos and Rialto Bridge very easily, but we loved staying in a neighborhood with locals and quiet back alleys. And if you want to visit Murano or Burano during your stay, you really can't get any closer to staying near the vaparetto stop. Thank you so much, Leonardo!
