We stayed one night as a part of a longer trip. It's a great location from which to visit the Château de Versailles. There is free underground parking which is very convenient.
The rooms are big and comfortable for a small family. The staff at reception were absolutely lovely and very helpful.
Our room unfortunately had an issue with the plumbing, and a very unpleasant smell was coming out of the sink by the toilet. As it became very noticeable only in the later eveving, and my son was asleep, I didn't notify reception until the morning after. The lovely gentleman there was very apologetic and said that they would have offered us a room change. I wish that I had done so, because the smell became intolerable as the night progressed.
Breakfast was nice. Simple, but it had everything we needed.
