We absolutely loved our stay. The place (both Gozo and the Airbnb) are magical. We stayed for a week and would have happily stayed longer.
We didn’t have a car (just bicycles), but got around easily on the bus (a 2-6 min walk from the Airbnb for the 303a and 303 buses, respectively). The buses are highly reliable and the Airbnb is an easy 30 min max bus ride to downtown Victoria/Rabat where we would enjoy the sights and/or easily transfer to buses to all other parts of the island. Alternatively, we took very reasonably-priced cabs to get to-and-fro from the opposite side of the island to our Airbnb in under 30 min for less than 10 euro.
Qala itself, the small village where the Airbnb is located, had everything we needed — multiple restaurants, bars, grocery, and a bakery — all within walking distance.
The residence itself is beyond charming and we felt very happy just spending the (odd rainy) day there reading and cooking.
Highly recommended.
