We stayed in the "Impiana Private Pool Villa" which is very spacious and well equipped, with the best view from the hill top looking down onto the Karon beach and the ocean.
The room is clean but do need some maintenance (e.g. one of the socket doesn't work, some pipes are not fixed onto the wall, some parts of the floor were worn out). Services are impressive. The scale of this hotel is small with only 11 villas - pros and cons - since it's so small it could not benefit from economies of scale and the price is thus high, and virtually no common facilities or amenities (save for a tiny gymnasium), but with a limited number of guests it means it is in general very quite and private (of course, depending on your luck and who are the other guests visiting there at the same time with you). Though located on the top of a small hill it is very accessible and both Kata Noi beach and Karon breach could be reached within 10 or 15 minutes walk, with abundant of shops and restaurants located along the Kata Noi beach.
One hint: since the hotel was built on and along a cliff, the view and floor plan of each room vary greatly with the landscape and height. Some rooms have real stunning view and large space while others may not have a view as good (but usually with more privacy), so you may ask the hotel for more information when deciding which room to reserve for.
