It is a very good located spacious apartment for any your route, and supermarket is in 200-300m from apartment - use the elevator on the street!:) Thery nice patio and really quiet street. Kitchen is very equipped! One of the best I ever see in my airbnb experience. Steve was a good host and helped us with everything!
It is very cmfortable to have 2 separate full bathrooms, but you need to keep in mind that taking a shower at the same time in both of them can be a little difficult because of amount of hot water. There is a rule not start washing or drying machine from 23 to 7.
There was not perfectly clean (but normal, the pace is nice and was cleaned), and I even saw ants in the kitchen, but maybe it can be usual thing in this region, like in Mexico, for example. Steve helped us with everything, as I said, and that's why nothing became a big problem.
Generally a good place to stay for family, can be recommended during your visit to Malta!:)
