Recently refurbished Casa San Carlo is one of the oldest buildings in Valletta. Until recently the building was occupied by as many as eight families in their own little units (which were called "Kerrejjas in Maltese) with their own front doors facing on to a common central court yard. In Casa San Carlo there are three rooms each on their own floor and served by a glass walled lift.
Bianca Apartment is located in a small block with 2 other apartments for holiday lets so guests need to be considerate to each other. In addition, there is a permanent resident who lives on the top floor and therefore the third floor is out of bounds.
