I had left behind my mobile phone on the plane and had trouble getting in touch with my family. When I told that to the hotel staff, to my surprise they offered me a free international call. In addition, they gave me a printout of an e-mail from my family in Japan addressed to me. They told me the travel information in detail. I was impressed by their hospitality.
The room was clean and the shower had hot water without any problem. The location is very convenient, close to the metro station and about a 15 minute walk from the Palais Garnier. I recommend staying here when you come to Paris.
