Apartment is great! Ramona and her family are very friendly and helpful people, was nice meeting them :)
Apartment is spacious and clean, air conditioners everywhere, loved loved the balcony with the grill. The only thing to note was sound isolation - You could hear everything in and out of apartment, but maybe that's all around Malta, because of the hot weather - they have thin walls.
Overall - Marsaskala is small but nice city, preferably stay here with car and travel around.
Advice for next visitors - Within 5min walk towards city is great bakery which unlike other shops is open all 7 days and always has fresh bread and basic food supplies :)
And do eat at LaFamilia, which is 4min down the same road where the bakery is.
