Just back from a great week's stay at Mario's. The apartment is modern, clean and well-equipped, and had more than enough space for two of us. It is well-located in the centre of Mellieha, less than 5 mins walk from the 'main square' and about 10-15 mins (downhill) to the nearest beach. We had a car and the drive over to Golden Bay, probably the nicest beach on the island, was less than 15 mins. There are some fantastic restaurants (Commando, Rebekah's, Amami) all within 10 mins walk. Communication from Mario was great and check-in very easy. Would definitely recommend, just take some earplugs for the incessant church bells if you're a light sleeper!
