There are several good options on where to stay in Luang Prabang.
I loved my hotel, La Residence Phou Vao, which is an Orient Express Hotel on the edge of town. The setting is wonderful with an infinity pool overlooking a mountain with a temple in the distance. They had a great restaurant, beautiful grounds and a spa. Their Lao massage, similar to a Thai massage, was great. I had a lovely suite overlooking the grounds. I highly recommend this great property.
Other recommendations we have been reading about include the boutique hotel, Hotel de la Paix, which has received several design acolades. There is also The 3 Nagas boutique hotel in town and the boutique Maison Souvannaphoum Hotel.
One of the newest luxury offerings is Aman Resort’s Amantaka Resort and Spa. This is a beautiful property on lush grounds.
