Becky's place is in a top spot in Valletta, near the fort and museum, very close to the sea, and just a couple of minutes walk away from the city center. She is very friendly and quick to respond or to help with anything you might need. She also offered to arrange the transportation from and to the airport, which was very thoughtful of her. In the apartment, you will find all amenities you may need in the kitchen (and more), as well as in the bathroom, so you may come relaxed and without any worries of forgetting something.
The place is also in a quiet part of the city, so even though the apartment isn't sound proof, you will have quiet nights.
The only thing I might say bothered me, is that there are no windows to open and let some fresh air inside. So each night when I got back from the town, the air inside was really bad and there wasn't much I could do about it.
