I had 2 days in the house and it was great but I would recommend to stay longer at the place is fantastic. The house is simple and beautiful, you are close to nature and all comfortable. The terrace has a full 180 view of the sea,and the volcano is whistling in the back. Karola is a great host who knows all about the island. The locals are extremely friendly and helpful so its easy to feel welcome.
If you go swimming get a snorkel! The walk to the point from where you can see the volcano is great to do at night!
