You will love this location in Birgu. Tonio's apartment puts you right in the centre of so many interesting historical sites and restaurants. It has all the amenities, great WiFi, large spaces and a great kitchen, including 'Mario' cafe (BirGi) who has great coffee and pastries on the street below. It was very easy getting to Valletta from Tonio's apartment by ferry and it was definitely worth purchasing a week's ticket vs doing daily trips; you can buy groceries in Valletta at the Food Market (awesome eatery and grocery options) or visit a great number of museums.
