This is a wonderful location to stay in Paris. So convenient to so many places.The flat is furnished beautifully with charm and care. You will be very comfortable. It is ideal for 1 or 2. There is some street noise from the skaters along the front of the Pierre and Marie curie institute but I actually liked listening to them. It was reassuring at the end of a day sightseeing. However, there were one or two nights when there were nighttime revellers. I was there in late October and the apartment was cosy warm.
Would highly recommend.
