I had an excellent time in Coco's apartment. It is small, but well decorated to maximize the space. I don't recommend bringing a lot of luggage, I had two large pieces and carrying it up and down the stairs was not fun. The apartment is located close to the metro and is a 10 minutes walk to the galleries Lafayette and gare du nord. All of the popular tourist attractions were easy to get to from Coco's, usually only taking 20 minutes on the metro to most places. Coco was was really helpful in answering any questions I had and even helped me to arrange a taxi to come pick me up to go to the airport. Would definitely stay again, just without all the luggage!
