We had a big family (5 adults, 2 toddlers, and a baby) one week stay. And it turned out to be much better than expected.
The place is outstanding, hosts have put a lot of effort into the house. All stuff is new and works perfectly, kitchen is very light and spacious, rain-showers, nice beds etc.
There are a lot of activities on site in case you stay inside: fast Internet, satellite tv, Netflix, pool table, board games, jakuzzi.
Benjamin was answering all our questions very fast and even helped us with socket adapters immediately (we did not expect Malta has UK style sockets).
Location is also a great point - 5 mins walking to the nice public beach, a lot of restaurants nearby and not too noisy in the evening.
Definitely will stay here next time I am in Malta!
