We had a lot of trouble finding this hotel, as the street changes names about 3 times, is one way in some places, and is a pedestrian-only street for a few blocks. The hotel is also tucked in a courtyard behind a wall, but we were very pleased once we arrived.
It was our first night, just off the trans-Atlantic flight with a day of sightseeing to prevent naps, and we were tired and delighted to discover how SILENT this hotel was. No traffic noises, no noisy neighbors, just pure, unadulterated quiet. I truly don't remember much about the rooms themselves--they were fine, but not especially luxurious, but the quiet was such a luxury itself!
It turns out this hotel is a member of the Relais de Silence, apparently an association of hotels offering especially quiet accommodations. Worth looking into if you want peace and quiet.
There is parking in the courtyard and behind the hotel, so your car is not out on the street. The people were very friendly and helpful in suggesting restaurants and the like.
