I stayed at Nathalie's for over three weeks. The apartment was in impeccable shape and close to the 1 & 8 metro lines. Nathalie uses a team to manage the apartment, and they were extremely responsive and helpful. During my three-week stay, I think I reached out to them once in the first two days and then had no reason to contact them until the last day. No fuss stay, extremely clean apartment, reliable for both short- and long-term stays. I think they adjust the price based on demand, but worth $400/night for two bedrooms if staying long term.
