Christian was a wonderful host. He was very communicative, timely when meeting us for check-in and flexible with our check-out time. He is so knowledgeable about the area and has tons of travel guide books to inspire your sightseeing plans. He's also really into music, so if you're a music fan he's especially helpful if you're looking for great music venues all around Paris.
The location of the apartment is wonderful - just a block away are bars, restaurants, and smaller wine and cheese shops but on Christian's block there are more retail shops that closed by late afternoon so it's pretty quiet and peaceful at night. It's a short walk to the Metro and about a 10 minute walk to more larger chain and affordable grocery stores like Franprix and Carrefour City.
The flat itself is a three-story duplex so if you're traveling in a group you can sort of find your own little nook to hang out in. The space is bright and airy with nice cool breezes throughout the day.
