Maria has a great apartment right next to the Upper Barrakka gardens. It is perfectly located for your to enjoy the small city of Valletta and is super close to the main bus station, which will make it very easy for you to plan your commute.
The apartment itself was super-clean. All the basic amenities are provided and we felt very much at home in the apartment. The shower area fits only one person and is a little tiny (tall individuals might find it difficult to accommodate themselves). We were there for 4 days and would definitely consider this apartment again the next we are in Malta.
