Me and my partner stayed in this apartment for 2 weeks. Being already familiar with Melieha, we knew the location is excellent - halfway between the large sandy beach (one of the best on Malta) and the main street of the town.
The photos don't do this place justice. It is very spacious, and all the furniture is brand new. There is a lot of amenities in the kitchen. The bathroom is in great condition, with a big shower and sparkling clean. The terrace has fantastic view of the bay from the hill and is very pleasant for hanging out in the evening.
The AC is prepaid (it is affordable, 10e will last you about 10 days), and Joseph will be very kind to start it up as soon as you arrive if you want. I wholeheartedly recommend it, because Malta in summer gets really hot.
Overall, I'm relatively new to Airbnb but this has been my best experience so far. I would recommend Joseph's place to anyone travelling to Malta!
