Excellent location, walking distance to many fantastic restaurants (highly recommend making a reservation for a degustation menu at L'Atelier des Augustins). There is also a bus stop nearby that makes getting around the city very convenient.
Check in and check out were very straightforward and handled via an agency. The walk from the building entrance to the actual apartment was a unique experience if you arrive after the sun has gone down and includes a walk up renaissance style stairs.
The apartment is lovely and very cosy.
We had a great stay and would love to return again the next time we are in Lyon.
