If you're looking for a nice, calm stay away from the hustle and bustle of Valletta, John's place will do the job nicely. It is a 3 minute walk from the bus stop and from there you can get all around the island (although the busses do take time). As well, if you're looking to go diving, the apartment is right down the street from GoDive Malta, the highest rated (on TripAdvisor) dive shop in Malta.
