I would still stay here again, but there are some things I would have liked to have known first to manage my expectations. The location is AMAZING - can't be beat. You are on the main street in Luang Prabang and can truly walk to everything in town (night market, best restaurants, sights, etc.). The monks walk directly past the hotel every morning for their food offerings.
The hotel itself is a small hotel, a historic property, and is comprised of two buildings across the street from each other. Rooms are on both sides. As a historic property, the rooms are all different, a little dark, and a little noisy. All of these were acceptable to me based on the fact that it is an old converted historic building and that was a reason for choosing it to begin with. The biggest problem for us, though, was the bathroom. The water temperature shifts from really hot to cool and back, making showering tricky. It seems like as a signature property of Sofitel's boutique MGallery line, this shouldn't happen.
The hotel offers bikes (which are fun to use) and you have access to the Sofitel property spa and pool (which we did not use). We loved being in the center of everything, and the service was fantastic - easy and user friendly. We also enjoyed the breakfast in the lounge which opens right on to the street to watch the world go by.
If I were to visit Luang Prabang again, I would still choose to stay here, but I would specifically ask for a room on an upper floor.
