I highly recommend Francesca's place. First, the host is very welcoming, nice and helpful, eager to answer questions and give information. Second, the place is great - the independent basement studio in a 19th century house is atmospheric, very nicely designed and equipped, with a lot of light from the street shafts. The location of the house couldn't be better - it is really the nicest street in Valletta, with historic architecture and an amazing view to the port and the Three Cities right across the street. So - do not hesitate to book it!
