Overall a lovely experience! Cécile is kind and the apartment is nice. The view of the city is AMAZING
Be aware: That view comes at a cost! If you plan to get around Lyon by walking (or by bus, depending on which busses you take), your way home includes a pretty steep uphill! I found it completely worth it, but if you have any disabilities that affect walking, this might not be the apartment for you
There is no air conditioning, as stated. I sort of assumed that there would at least be a fan, but there was not (to be fair, I didn't ask). So for a June stay it was HOT and I found it difficult to sleep some nights
Also - and perhaps this is already getting fixed - there is a piece broken in the shower. It's one of those hand-held showerheads, and there's supposed to be a part that will hold it up for you, but that part is broken. So you have to either hold the showerhead or set it down carefully on the floor. Not the worst thing in the world, but an unexpected additional challenge!
