I would definitely recommend Ian&Anna's place to those that go to Malta for work as I did. The place is well connected to the rest of the island but if you decide to go to La Valletta on foot that's also easily feasible, in fact I enjoyed my walks every day of my stay.
The apartment is bigger that in photos and it is a great place to work on your laptops, even from the roof terrace. I didn't find it noisy at all, at least not noisier than the other places in Malta- Mediterranean people are quite lively people which I think it's great!
Thank you Ian& Anna! I will definitely come back when I have the chance.
