We stayed for a week in Nicolas' flat and truly enjoyed it! The flat is perfect for a couple or 2 people, very modern and well decorated. We found the location perfect as taking day trips to Versailles, champagne, etc close to train station. In non touristy, real Parisian section of city, easy to walk to Marais or Canal St Martin, my favorites, or metro anywhere. The 5 stairs up is not for the weak of heart, no elevator, this is typical in Paris. I highly recommend this apartment and hope to stay again on my next visit.
