We stayed one night but wished for more. The rooms are lovely and very comfortable, large, high ceilinged, basically a series of duplex cabins arranged the central reception and dining facility. It's a thoughtfully designed property. The restaurant is open to the air and up on the second floor where it catches the breeze. From the restaurant are nice views of Sigiriya off in the distance. The food was excellent. The chef, who showed an owner's attention to detail, has a lovely manner. Despite lots of water features on the grounds, most planted with lilies, we were not bothered by mosquitos at all--and if they were around we'd know. The staff was friendly and highly responsive any time of day or night. The route we followed to get there from Sigiriya was a crazy bumpy, dirt pot holed road. But it was more than worth it (and it's really not that far).
Was everything perfect? no. As others have commented it's new and the plantings have not grown in yet. We found it quite attractive though and as things grow up it will have a more lush and established feel. The hot tub is big,nice for two but the hot water comes from a point of use heater and so it took about 45 minutes to fill the tub--plan ahead.
All in all we highly recommend it.
