This is a lovely AirBnb that comfortably housed our family of six (my husband and I, our 3 teen daughters, and my mother) during our 3-night stay in Lyon. The kitchen is particularly spacious and well-equipped, and the main living area is homey and comfortable. Valérie and Jean-Christophe are easily among the most responsive, helpful hosts I have encountered during my many AirBnB stays, going the extra mile to make sure their guests have everything they need to feel at home.
The layout of the home is somewhat unusual, as all bedrooms are down a metal spiral staircase from the kitchen and living room. There is a large, well-equipped bathroom downstairs, with a gorgeous whirlpool bath and washing machine. There is another toilet on that same level, next to the master bedroom, which also has a large shower and small sink/mirror area. All bedrooms are roomy and comfortable, and the street noise was never so bad that any of us were kept awake. The only issue we had with the space was for my husband, who is 6'4" tall (1.93m). The doorways on the lower level were so low that it was sort of a miracle he didn't knock himself unconscious. I suspect people with bad knees or difficulty with stairs should also look elsewhere, as you end up going up and down the spiral staircase many times throughout the day, including when you haul your suitcase up and down with you and the beginning and end of your stay!
Speaking of walking up and down, as other reviewers have noted, yes, the flat is located on a hill, and a steep one at that. It's not the easiest place to get to, but the nearby funiculaire definitely makes it easier than it would be otherwise. That being said, there is a small park across the street with spectacular views of the Saône River and surrounding architecture. I should also note that we were in Lyon at the beginning of a record-shattering heatwave, and I suspect that under normal weather circumstances, none of us would have minded the climb much. The proximity to Vieux Lyon was a definite plus, and I highly recommend devoting some time to wandering around that part of the city. If you're looking to have the best burger of your life, be sure to have a meal at Cosy Corner. I had the My Ducky and I'm pretty sure it changed my life.
