This is a beautiful and quiet place in an excellent location surrounded by restaurants, bakeries, cheese shops, anything you need, really. The patio outside is a wonderful place to sip some wine after a day of exploration.
As reflected in our review, we had some major issues with checking in and communication. We were not able to drop off our luggage at the apartment (as previously arranged) and stood outside the main door of the building for an hour, calling the owners (to no avail) and banging on the door, in 42 degrees heat after a 16-hour journey. We finally dragged our luggage to the nearest restaurant (Le Temps des Cerises - excellent and authentic) and had lunch. I left the family before dessert and walked back to the apartment and called the owners again (no reply) and banged on the door. A woman showed up - the caretaker (a very nice woman). She eventually took us upstairs and explained in halting english (she spoke no french) where things were. There was no booklet (as we have seen in numerous AirBnb's) explaining the different facets and quirks of the apartment, and no information about the area. The wifi code was found, almost by chance, scribbled on a scrap of paper.
Later: My wife and I went grocery shopping and left the kids in the apartment. Upon our return (loaded with bags of food), we punched in the code to get in at the bottom of the building. It didn't work. We tried for one hour to access the building, called Emmanuel and Juliette (the owners) countless times (to no avail), called AirBnb (they were useless), and, as the battery on our cell phones was dying, finally managed to rouse our kids to come down and get us at the bottom. The caretaker had mistranscribed the code.
Emmanuel and Juliette finally got a hold of us in the evening. It turns out they were out of cell phone range in the cool and clement climate of Brittany as we were baking outside their door. They were nice enough to credit us one night but, frankly, we would have been happy to pay double for that one night if it had spared us the ordeal. I see from other reviews that other guests were happy with communication, so I can only conclude that is was an isolated incident.
One last thing: We arrived in Paris in an unprecedented heat wave. Not a puff of wind. The bedrooms upstairs were convection ovens. We all slept (camped) on the main floor the whole week, with windows wide open and serious fans blowing hot air. This beautiful apartment would have been a dream in spring and fall, or a cooler summer (but it looks like we won't be getting those anymore).
