A very French experience and the location was perfect for us. It was easy walking distance from both Sciences Po campus and the Cathedral. Many excellent restaurants and shops nearby.
The staff was friendly and helpful. The building was quaint with a lovely courtyard. The Continental breakfast was very good, but perhaps not what some American might expect. Our room was small but adequate.
The only thing that was a problem for us was that the wi-fi did not work well on the 2nd floor. Also, the front desk is not open 24 hours a day. Make sure the hotel is aware of your arrival time. I think they can give you a code that will give you access to your room key, but you might ask them before you arrive.
If you are looking for a French experience, this is a good choice. If you "need" an American hotel, try the Best Western :)
