Great location. Great value. This is the best neighborhood in Paris, in my opinion, and Gary's apartment is perfectly located, only a 2 minute walk from the Odeon metro stop and right on a bus line. There are many shops, bakeries, grocers, and restaurants within steps of the front door.
The building is an older typical Parisian walkup, but the apartment is up only one flight of stairs. The apartment is a studio, but the kitchen area and bathroom are plenty big. I was there for four days as a single traveler and found it very satisfactory for cooking, lounging, and sleeping.
Gary was quick to respond to my communications. In fact HE called ME as we approached our appointed meeting time. He was very friendly and explained all of the systems in the apartment (heating, tv, wifi, etc.). I would certainly return to this AirBnB on my next visit to Paris.
