Apartment is large for Paris. It is very well equipped with the latest appliances. It is off an two inner courtyards - living room / kitchen face one courtyard with a business across the court. Business is occupied until about 7:30 at night. Bedrooms face another courtyard. Therefore you do not get street noise, but do get some of the noise during the day from people taking a break from their jobs and talking in the courtyards. There is some noise around 7:30 in the a.m. from apartment above - moving around of things.
Apartment is convenient to metro 2 & 4 lines and about a 10 min walk to Gare du Nord. Scare Coeur is in the neighborhood. Overall a very comfortable apartment. Self check in. Vanessa was very responsive about missing garbage bags and had some sent over right away.
