We stayed a few days at Marias place. Unfortunately she couldn't welcome us in person but a friend of hers who just lives a few houses next to the location was available which worked out fine. The apartment is awesome and the location is just perfect to enjoy Valletta! Keep in mind, the apartment is located on a street with stairs. Parking might be challenging, but as we were using public transport it worked out fine. During our stay constructions were going on at the street close by which made it impossible to sleep longer than 8am. The airconditioning is your friend as the windows don't have any shades to keep the bugs away! We'd stay there again! We've been also welcomed with a nice bottle of wine and a book that contained a few infos about valletta.
