I had a great stay at Elaines place. The apartment was spotless clean and very well equipped (e.g. there is an ironing board and iron which is very useful).
The apartment is located in a calm, residential area, just a couple of minutes away from the promenade, where you can take long walks along the seaside.
Marsaskala was one of my favorite spots in Malta, quiet and peaceful with hardly any tourists.
Elaine is a lovely host, very quick to respond to all questions you might have. She provided me with an information booklet, containing useful tips around the apartment, recommendations where to go in Malta, where to eat etc.
Would 100% recommend this place.
