We stayed there last January 2007 for 4 nights in Luang Prabang. The guest house s location is convenient and perfect right in the centre of the historic town. However, as we booked by email the night before our arrival, we were charged US$24 a night which is overpriced for what it was, although I guess we had one of the best rooms of the guesthouse. Although the room was clean, there were a lot of small details which made the stay not so comfortable: the blanket was too short for the bed (it's very cold at night in Luang Prabang in January!), the room was quite noisy because it is surrounded by other guest houses with noisy people, the bathroom was also very noisy (at night, we heard every water noise from next door's bathroom...) and there were problems with the pipes, and finally, the hot water dit not function very well.. the water was warm but more cold than warm... And there were no place to put/hang the clothes anywhere in the room or the bathroom, as if the room was built for short term stay (one night stay) only.
Although the staff was friendly, I think the room did not deserve a US$24 rate. US$10-15 is OK for that, but not 24.

This guesthouse is between the main street and the Mekong, a great location for walking to both. Resturants nearby and a fast internet cafe across the street. Prices start at $15. for one or two. Large rooms, nice staff tho not overly friendly.
