Very poor service, did an error in booking over a month in advance and tried to change it. Tried calling, mailing and going through the booking, was in Paris and also went in person but there was no helpfulness at all, just met with disinterest. Was making a point in being polite and humble, despite this no help.
Seemed also a bit umkempt from the appearance of the reception area. Never saw a room.
Good location for the train, but would choose another hotel in the future.
