We spent 3 nights at La Maison D'Angkor and loved every minute of it. The small setting provides a perfect escape from the intensity of SR and busy days of temple viewing. The rooms are tastefully done, and the facilities (including spa, jacuzzi and swimming pool) were first class.
The staff were great - eager to please, friendly and well trained. Our tuktuk driver spent the whole time with us, and was not only able to provide information on the different temples, but also on other sites, including various sites of interest around Tonle Sap.
I would highly recommend La Maison D'Angkor to anyone spending time in Siam Reap.
