Andy's place was great!
I stayed there for a little more than 5 weeks, as I was working in Malta, and I felt at home from the first moment on :) My wife and two kids joined me for the last week, and they loved it, too!
The location is great - 1 minute from the beach, 2 minutes from some corner shops, 10 minutes from Bugibba Square. And in spite of the central location rather quiet at night - especially for Malta :)
The place is clean, spacious and modern, it has everything you need, eating on the roof is just wonderful, the ACs are good too (and they didn't give me a headache like most AC units).
The only thing that needs to be said is: You must climb the stairs up to the 3rd floor - not a problem for me, my wife and our kids, but it might be an issue for some people.
Andy and Mac (who lives in the same building and is always there to help) were great hosts and bent over backwards to make sure my / our stay was a pleasant one!
Highly recommended, and I hope to be staying there again when I return to Malta!
