For your stay in Marsalforn you can't go wrong with Victor! The flat is as on the pics with a balcony facing the ocean. From here you can easily explore the island by bus or rent an bike and explore the near surrounding.
Victor is a nice and helpful guy!
Since it is right on the beachfront above restaurants: you are close if you want to go out, but don't expect romantic evenings on the balcony (noise).
