We stayed at the Lokha for 5 nights on our honeymoon on the basis of their being a lot do and see in Ubud and the surrounding areas. We really enjoyed visiting Ubud as it has a good nightlife and many restaurants and there are a lot of cool places to visit by car.
First impressions of the hotel were good, its a little out the way and you have to go on single track roads to get there but once you do the hotel is unique and covers a hill overlooking the rain forrest and river. The lobby has wonderful views of the rain forest.
While the lobby and rooms are nice and modern we found that it was difficult to relax in the resort due to it being in the rain forest and their being insects everywhere you looked. For a few nights it would be fine but the longer we stayed there we yearned for simple things like a mozzie free night and to relax by the pool - to put it in context the restaurant is outdoors and a lot of insects would be around all the public areas, we had 20 mozzie bites between us on checkout, this was the only place in Bali we had mozzie bites.
In the end we cut the stay short as we couldn't relax in the hotel and it was impacting our honeymoon, we went back to the south of the island.
The hotel wouldn't refund us the night we lost which was really poor customer service, in addition the staff were not as friendly or experienced as the other hotels we stayed at.
Another sore point was having to pay to use the jacuzzi and sauna in the spa! For a nice hotel we would have expected these to be included.
