My husband and I stayed in Lee Lee's Parisian flat this past weekend in Le Marais. The neighborhood is perfect alone, happy hours on every corner (some until 2am). There are tons of shops and restaruants, clubs, bars, etc... large area and close to several train stations. It's about 45 mins from CDG (trains or taxi) and 25 minutes from Orly (via taxi for Orly.
The apartment is beautiful and clean, bed is supppper comfy. she did a great job at decorarting. At first we were thrown off by the entrance, it reminds me of a speakeasy but we ended up falling in love with the Parisian flair. There's a supermarket almost directly across the street and 2 cool bars at the end, like 2 minutes. The street is quiet, and though it's a small alley like street, we felt safe at all times. I would definitely stay here again. Lee Lee was quick to respond, easy going, and left a map and suggestion book for us with bottled water.
