Mario's and Rita's rooftop appartement is just a wonderful place. The view from the top to Valletta and the harbour is amazing. It's a very quiet location, but it's very closed to the ferry (max 10' walk) that brings you in 5' to Valletta. The shared kitchen and terrace makes it even more worth. Mario and Rita are great hosts. They give you lot of helpful information. Don't hesitate to ask them for any need. The communication was very easy. They also offer airport Transfer and other trips to a reasonable price. I'd recommend it to everybody who wants to explore Valletta and surroundings.
