Apartment is small (as are most places in Paris), but has everything and more you might need. The location is fabulous and convenient to restaurants, excellent bakeries, and even a large grocery store. The metro/RER is easily accessible, and you are able to get to CDG Airport without having to change trains - a plus when you are hauling luggage. This is my favorite area of town as you are within walking distance of most, if not all, tourist hotspots. It is also close to St.-Sulpice, which is a bit under the touristy radar, but definitely worth visiting. I would absolutely stay here again.
John was an excellent host and made everything easy for us. The apartment was spotless and had lots of cool smart features. Book this place - you won't be disappointed!
