It's a very spacious apartment with a terrific 3rd floor veranda view over St. Paul's bay to the left and classic Maltese hillside to the right.
Bedrooms are air conditioned, the hosts provided laundry liquid for the washing machine. Very close to the apartment is a heritage trail with archaic cart ruts (like Pompeii) and a Roman bathhouse cut into the hillside - worth a look.
Location: it's in the north west of the island which is close to the best beaches. It's great to punch "home" in on the sat nav after a day snorkeling for it to say "11 mins". We stayed a week and didn't go to the same beach twice. Parking was fine on street as long as you don't expect to be immediately opposite the flat.
I spent a bit more than I wanted on this apartment because it looked nice and I wasn't disappointed. Overall it was a great base to explore and we'd come again.
