Charlie's place is great for visiting Paris. I was there for a work conference and it worked out great. It's just 10-15' from Gare du Nord and near many cool places to visit. In addition, the apartment is just 2' away from the Cadet metro station. The apartment is quiet, clean and with new amenities. Although the apartment is on a 6th floor, I actually enjoyed going up and down and took it as motivation for keeping myself active during my busy work days. Merci!
