A great spot! While I was only there for a one night layover between train journeys, Pierre made sure that I was comfortable and met me outside the building when I checked in to make sure I understood how access worked. The room I stayed in was clean and neat and the dedicated bathroom space for guests was greatly appreciated. Additionally, the roof space has incredible views of the Paris skyline. While unfortunately I was there in December and couldn't take advantage of this feature, it would make for a great part of a trip during warmer months. Thanks again Pierre!
