The walls in the hotel were very thin. You could hear the televisions and conversations from the rooms next door. Also, the lift is very small and from the sounds of it, it needs a good service.
The room itself was very warm, especially at night. We used the air conditioning but it wasn't that great, we had to end up opening the window. It possibly just needs an upgrade
The hotel was so easily accessible from CDG on the RER, closest station was the Luxembourg station, which is around 5/10 minute walk from the hotel.
Also, the Notre Dame Cathedral is also very close, another 10 minute walk.
The hotel is modern and classy. The staff were extremely helpful and spoke great English.
The room, while small, was perfect for our stay. The bed and pillows were so comfortable, which was great after a long day walking in the city. The room was very clean and the bathroom was lovely. A great shower with lovely bath products.
All in all, a beautiful hotel, we didn't want to leave.
