Good location close to a good number of restaurants and bars along with the shopping in Sliema and access to ferries/buses to Valletta.
My wife and my parents stayed at Paula's apartment for one week over Christmas. The apartment was well-equipped, comfortable and in good order.
Paula although overseas herself was easy to contact and promptly sorted out a couple of problems that we experienced during our stay (not enough towels had been provided) . The transfers she arranged for us were punctual and our stay was pleasant.
If I had one complaint it would be that we felt a little cold at times even though we had the heater on it didn't seem to warm up the apartment very well. As I understand it this is a common theme for most properties in Malta, they're built for the hot weather and not the rare cold spells!
