The appartment was as it was described, spacious and well located. For a family 2+2 we had more than enough space. Paula was very helpful and quick in answering e-mails. We shut the door with the key left in the lock from the inside so it was impossible to open the door, she found a locksmith within 10 min.
I recommend very much transfer to and from the airport. Lino (driver) is the best guy ever, he told us a lot about history of Malta and showed interesting things (which you will not fing in the guide) on the way to the airport.
Shops, restaurants, bus station, car rentals are 5 min walk from the appartment.
