The apartment is great, well-equipped. We used the wash-machine almost every day :) In the living room, there is a coin operated AC system, pity it isn't installed in the bedroom, but the cooling fans are great too:)
The neighborhood is safe and calm. You can find a bakery and grocery very close to the apartment. The beaches are a little bit far (40 min by bus, the closest). Valletta 45 min by bus.
Matthew is a great and helpful host! I recommend his apartment!
