This is a fairly basic apartment (not in a bad way) in a lively neighbourhood, about 15 minutes walk from Gare du Nord. The area is good for restaurants and nightlife, but the flat itself is in a quiet courtyard so you get the best of both worlds.
Communication with Jean was great. The flat is very clean and the WiFi is excellent. If you want a small and (thankfully) quiet base for business or a short leisure stay this is an excellent location.
