Meets the AirBnB trifecta: safe, clean, convenient. Five minutes' walk from Gare du Nord, a major transit point. The building is old, but the unit itself is modern and sleek with charming touches like vintage moldings. Franck was easily reachable, helpful and kind. He lives next door, which can come in handy. Only caveat I'd add is that it's a fifth-floor walkup, so pack light and don't skip Leg Day at the gym!
