Great location, easy to get to, 10 min walk from bus station for buses to and from airport and the rest of the island. Sally port cafe, great for morning coffees on the terrace or for a pizza in the evening, it is popular so be prepared to wait. Supermarket also right across the street and probably the best one in Valletta as it stocks everything.
The house is literally a 5 min walk from the main high street, but would recommend wandering down the little side streets for authentic Malta. Excellent value for money all round.
Would highly recommend.
