The pictures tell the story well, a fantastic villa on a mountain top, with a fantastic view over the sea. The beach (with restaurant) is really close (2 km.) and the north of the island is really nice. Far away from all the noise and other tourists, buth close enough to everything you need (beaches, restaurants, hippie market and supermarket).
The house was very clean and everything you need, can be found (dishwasher, multiple showers, bbq, tv etc). The only idea is perhaps to rent a car which easily can manage the somewhat challeging road to the house. Specially the last 400 metres is with a regular vehicle a bit challeging, but after some days of practise, it becomes more easy. No reason not to go!!
We stayed at the house with nine people (4 adults) which was very okay.
The beach Cala Pada at the East coast (20 minutes) is really nice, small but with everything you need (nice restaurant with fantastic food on the beach), also on Saturday there is a small (and authentic) hippie market in San Joan (10 minutes). Also the small supermarket in San Joan offers everything you need. The butcher has very nice meet for the bbq!
Summary: don't hesitate to book this house.
