You can't beat the location of this AirBnb! All of Valetta's major sights - yes, all of them - are within walking distance, and a large number of restaurants, bars and cafés are just a 1-2 minute walk away. The apartment itself is located in a very quiet side street with no traffic noise. The hosts are very pleasant and quick to respond - we had a problem with the electricity (not the owners' fault) and someone came by within five minutes.
The amenities of the apartment are very basic, offering everything you need for a short stay but not more, which is okay because the place is cheap. Some extras such as tea/coffee or water would have been much appreciated. We had some issues with water pressure in the shower and with humidity. Be advised that the place can get quite cold in the winter! There is an AC upstairs (which unfortunately we couldn't get to work properly), but none downstairs it seems.
