It's a lovely house, right in the center of Marsaskala. Plenty of delicious food right across the street, all within walking distance from the beach.
The house is huge and freshly renovated, easily accommodating the 4 of us and 2 dogs during our working holiday.
The driveway is very short, so if you have a standard-size car you might have to find a parking space on the street, which is always doable (we never had to walk more than a couple of minutes from where we left the car).
Mark was a great host. Our trip was delayed by over a week due to bad weather and he agreed to reschedule our stay without any trouble.
