Cute apartment in a great location (probably the coolest neighborhood in Paris with just about the best transit access and walkability you'll find anywhere in the world). Charles-Henry had lots of suggestions for coffee and restaurants, and a very smooth check-in/check-out process. (He even left us a bottle of champagne and a kind note.) This place is what makes Airbnb great: you get a small but real taste of what it's like to be a local.
One thing worth noting: this isn't the place to go if you have a mobile young child. It's a beautiful home that's lovingly maintained and there's a lot of stuff (artwork, furniture, marble) for a child to ruin. We didn't read the listing as carefully as we should've and were just lucky that our baby can't crawl yet. I want to be clear I'm not criticizing Charles-Henry -- the listing in no way implied it's particularly kid-friendly. Just mentioning for any exhausted parents of toddlers who don't read listings carefully either.
