The Vittoriosa apartment is wonderful - very cozy and well situated in one of the three cities. It has easy access to water taxis that will take you to Valletta, and a 2 minute walk from a gorgeous harbour view. The bus is #2, stopping at Bormla, which takes you to Valletta to get to other buses (runs about 20 minutes). Mariella was a great host - picking us up from the airport, printing boarding passes, and providing advice.
