This is a great place, to use as a home base for Paris. The walk to the Metro is fairly short, and--zip--it gets you all around. The neighborhood around the Paris Circus is interesting full of great places. And in my years of AirBNB, I've never seen such great suggestions as the one that Bertrand gives to his guests.
The home itself is an old store front turned into an upside down apartment. It is an unusual space and it is decorated in an incredibly fun way. My kids 6, 9, 12 loved it. One tip: If you have a kid who is likely to be overwhelmed by sensory overload (my 15 y.o.) you will want to prep them for the stay, because the Paris Circus really does have a circus / fun house feel. I wish I'd shown my older daughter photos so that she could have gotten the sense of the place before hand. She was a bit shell shocked when we walked in originally. Once she got over the shock--no issues. The kitchen is good and the shower is great.
Definitely would use again when and if we return to Paris.
