Great location, 5-minutes walk from Gare du Nord and several metro stations. The apartment is clean, very cozy and has everything you need for a comfortable city trip. We didn't meet Isabelle because we picked up the keys in the locker at the station, but she provided all the information and tips about restaurants etc in the area, as well as lots of tourists books about Paris. Internet didn't work well, but I think this was a problem with the server. Would definitely recommend this apartment if you're coming to Paris!
