When we walked in the door of the apartment on arrival, my 13-year old turned to me and said, "Mom, THIS IS THE BEST AIRBNB EVER!". My entire family agreed (and we've stayed in quite a few airbnbs).
One bedroom has a loft bed, perfect for our 12-year old. Another has bunk beds, and another has a queen bed. The bathtub probably could have fit all of us at once. The kitchen had everything we could have possibly have needed. The decor was incredible! Our eldest daughter spent the first hour just taking pictures of all the antiques. And it was very clean and well-organized.
And the terrace! I can't even begin to describe how lovely it was for morning coffee. It is quite large with very comfortable loungers and a small table for dining. At night, my husband and I spent hours just sitting and relaxing. There were candles everywhere, and the bamboo made a partial canopy, giving us plenty of privacy.
There are several bakeries and restaurants nearby, and Ludovic kindly provided a comprehensive list of places. He was very helpful via email, and regularly checked in to make sure everything was okay. the area is quite nice, central but not touristy at all. Jacques Bonsergent metro is very close, and it's easy walking distance to the hip Republique/Oberkampf area (also to Bastille, although it's a bit farther).
I had spent hours looking for a place in Paris--I'm so glad we chose Ludovic's. We would stay there again in a heartbeat. Thank you, Ludovic!
