we have made the reservation 3 weeks ahead before our arrival by handphone (they do not have any other facilities to be contacted to)
Asking Mr Leo, the man who is in charge with the hotel to send us the short message by celular phone for the confirmation - only promises, he never sent any
arriving at the hotel, they do not prepare the room with ac for us, as he's promised
the room is okay, clean without hot water
you have to wait for breakfast
The room is okay, the bathroom is a little bit poor
the double bed just too small especialy for the big person

Never try to rent boat from him
He just ripped off the customer

If we may suggest, skip riung to safe your time. the road is so bad, takes ages to reach there. the people there like to cheat - they try not to bring us to the place which is good for diving with lots of reasons. they just take us to the closest place they want, and if we are loosing our mood, they don't feel bad to take us back to the hotel even we haven't got our good space for scuba dive

My husband and I stayed there for 2 nights in July 2012 in room n.115 with AC but only cold water.
The accommodation is very basic and, though they say it’s pretty new, it already seems in need of renovation! The room was large but not so clean, bed was comfortable but sheets and towels weren’t very good. Bathroom was really basic, too: my husband had to fix the sink faucet because we had no water and they couldn’t do it! Lack of toilet paper. AC not working very well. There was a lot of noise from the generator (from 6 pm to 6 am) and from the people who were supposed to work there and instead spent their time chatting loudly and listening to the music in the porch outside our room. Breakfast was terrible: horrible banana pancake, scramble eggs, the/coffee in not so cleaned dishes.
Obviously, one goes to Riung to take a boat to visit some of the “17 Islands” that are really beautiful, but the road to/from Riung, though a bit bumpy, is very scenic, too!
In Riung we had dinner at Rumah Makan Murah Muriah restaurant: very good cooking and they speak good English, too!
