The first evening, we were unable to turn the lock on the door to our room. Our door stayed open but we had a dinner date with friends nearby so had to leave the door ajar. We called Fede, and she hired a locksmith who came immediately from Mestre on a Saturday evening to install a new lock and key. All was solved in a couple of hours while we were out to dinner, and we were able to sleep with our room door safely closed and locked when we returned. Communication with Fede was swift and efficient. Breakfast was abundant and the coffee was delicious. I would definitely go back as it is very convenient to the Giardini of the Art Biennale and is in a less touristy and quiet part of Venice. Next time, I'll book earlier for a room on a lower level, though. The three-story climb was tough after a day of sightseeing. It is a small air b and b with about 6 rooms. The other guests were friendly. Everything was super clean, the bed was comfortable and the view out the window, quaint, overlooking some tiled rooftops.
