The cave house offers a great view of the sea, and is located extremely close to the famous three blue domes. The place is exactly as described by the pictures: spacious, and nicely decorated.
The steps leading to the house can be quite steep, especially the section just beside the blue domes, so be careful when walking down. But other than that, the location is quiet, which offers a lot of privacy.
It's a great place to stay, and I would definitely recommend it.
