We stayed at this apartment for 3 nights. The location is highly recommendable. Things to take note have already been mentioned in other reviews: The apartment is on the 5th floor without elevator, which can be a challenge, and it is indeed somewhat smaller than it looks on the photos. That said, it was a perfect base for us to visit Lyon. You are right at the entrance of the main street of old twon Lyon and there are 2 amazing bakeries next door for a cheap breakfast.
The apartment was clean and had everything we needed, communication was good. One more thing: In order to lock the apartment door, you need to move the handle down, then up. This was not directly clear to us and took some time to find out. We would definitely stay here again (as long as we're fit enough for the stairs).
