Amazing. Jean-Michel was a wonderful host and helped us with any questions we had at any given time. When we were unable to make a restaurant reservation due to language issues, he was great and did it for us. Toilet paper out? He left us a new roll on the door. He's a very nice man, and he really cares about his apartment. This is evident via his amazing orientation guide to the apartment and cleanliness.
For the area, Le Marais, this is a perfect spot to situate oneself in the center of Paris within walking distance to everything. For those out of reach sights, like Versailles and the ADT, the metro stop is literally right outside one block south towards the river. Easy to use!
We highly recommend staying here. I couldn't be more content and more ready to return to Paris (I'm writing this in the airport ready to leave). I'd be sure to book with Jean-Michel again next time.
