We've ended up at Mario's because our first airbnb in Gozo was not available for the whole duration of our stay. But at the end, we wished we had stayed here for the whole week. The accommodation is spacious and extremely well equipped. The wifi is very good and there is a TV with apple tv with Netflix. We really enjoyed the fact that it has a real home feel. Too many airbnb these days are just similar ikea type déco. Here, it felt home. Maybe your parent's or your grandparent's home, depending on your age, but home. The location is remote enough from the centre that you don't have to listen to the traffic but close enough to walk there. It took about 15-20mn to reach the citadel. 4mn by car. There is a couple of restaurants nearby but I can't comment on them as we haven't been. There's also a small shop fairly well stocked. It is a good location to explore Gozo.
Not many minuses, the shower was a bit on the small side but still OK. In the previous airbnb, we were woken up by the delivery truck which was frankly annoying, here no truck but you'll have to deal with the Rooster morning singing. Not a downside for us, we actually enjoy this, but others might see this as a nuisance.
Mario and his wife are lovely couple, we enjoyed meeting them and we'd definitely come back to their airbnb if we come back to Gozo
