I‘ve stayed six weeks at Mario‘s flat and I can definitely recommend it.
It has been clean, modern and close to the centre of marsaskala. Whenever I had a question or needed something I could contact Mario, so communication was very good and easy. He even prepared a booklet with helpful tips on bus service and information about Malta. The bus stop in front of the house made traveling quite easy.
Mario and his wife are lovely people and I felt welcomed and safe :)
