Gary's place is in a GREAT location, very close to both the metro and the RER B and also within walking distance to things like the Seine, Notre Dame, and (this one's a long walk, but doable) the Louvre. There are plenty of cafes, supermarkets and boulangeries in the area, but it's not a very touristy area so it's also pretty quiet at night. There was enough space for the 4 of us, and we even cooked a bit in the cute kitchen. The only downside was that the bathroom door is a curtain, which was fine for all of us (it's through the bedroom anyway, so if no one is sleeping it's also possible to just close the bedroom door!), but it's something that is good to know beforehand, depending on who you are planning to share the place with. :) Gary was flexible with our check-out time, so we basically could stay until our flights left which was very, very nice. We didn't get to meet Gary, but he was very helpful with arranging our stay via air b&b messages, and we would definitely stay at his place again. Thanks Gary!
