I stayed here while doing research at the university. Valletta is of course a little far from Msida, but it’s totally worth being in a beautiful old neighborhood with lots of great food nearby. The apartment itself is cozy and any dampness is rectified by the dehumidifier near the kitchen. The location is perfect—it’s very close to restaurants and the main streets, but far enough away that even on La Notte Bianca noise was at a minimum. It has everything you need for a longer stay, and would probably also be great for a shorter visit.
