Traveller reviews

“Well located comfortable hotel”
06 Jun 2025
Decent sized bedroom for Paris, in a good location

“Lovely Hotel!”
31 May 2025
The room was great! Well-designed, lots of room, luxurious, and very comfortable. Cool old-school elevator. Staff were excellent and accommodating. A lot of hotels change over from heating to cooling at this time of year, so the air conditioning doesn't always come on the way it should. Our first room, that was the case. They gave us another room with a working air conditioner, and an upgrade. So, thank you very much.

“Quiet, bt well located and equiped hotel.”
05 May 2025
Great location for discovery of Paris. Despite close to shopping, quiet street. Comfortable rooms. Good restaurantfor both breakfsst and dinner.

“Overall hotel staff helpful - restaurant staff went above and beyond and could not be more helpful.”
27 Apr 2025
The restaurant staff were extremely helpful and professional. Nothing was too much trouble and the staff recognised us from a previous visit in December 2024. The quality of the food there was also excellent
