Location, location, location! This apartment is in really good location with awesome views from it's balcony and neighborhood is really quiet area even it is so close the center of the Valletta. Also, there is a ferry terminal just by the sea in 10min walk away, where you can get ferry to the three cities or even to the Gozo island.
Apartment is really nice and spacy and it has all home appliances you need and air-condition makes sure temperature in the apartment is what you like it to be.
Robert gave us lot's of good tips from Valletta, where to find the best restaurants, shops etc. and is really good and trustful host!
10 days went just too quick, but I can really suggest Valletta as your vacation destination.
