Sylvie's communications were outstanding before and during our stay. She responded virtually immediately and extremely helpfully to all of my queries and she has a warm, approachable and friendly tone. She was out of town during our visit, so we didn't meet her, but her directions to the apartment and detailed check-in instructions were typically clear and helpful.
Sylvie's apartment is wonderfully spacious, with lots of natural light, and is tastefully decorated. with a lovely atmosphere. She left milk in the fridge and some essential products so that we could have a light breakfast each day and I can't think of anything I would want, which she didn't provide. The main living space encompasses a lounge-type area and a kitchen and its high ceiling and generous dimensions made for a very comfortable experience.
The bathroom is far more pleasant than most apartments I have been in and the shower area was spacious and - like the rest of the apartment - spotlessly clean. The only minor issue we encountered was that the warm water supply didn't seem to extend to consecutive showers so it might be advisable to allow the system a little time to "recover" before taking a shower after your companion, or be prepared for lukewarm water. This wasn't a problem for us and I strongly suspect that it is a feature of the type of apartment block, and which Sylvie has no influence over.
As others have reported, the apartment is in a hilly area but we found it perfectly manageable. We used Lyon's Metro system extensively and found it easily navigable with frequent services. From the airport, we took the Rhone Express service and got off at Vaulx-en-Velin / La Soie [rather than staying on until Part Dieu], then took the "A" line on the Metro to Hotel de Ville, changing onto the "C" line for one further stop to Croix Paquet. From there, it was a few minutes' walk to the apartment.
For a big city, Lyon somehow had the feel of a smaller town, with very friendly people and none of the "edge" one might expect in places like London, Paris etc. It's a fine place to wander around, with a hugely attractive old town and we could happily have spent longer than the two nights we were there.
If you are looking for a restaurant different from Lyon's traditional "bouchons", you might consider Café Sillon which was atmospheric and stylish with lovely waiting staff, innovative and very tasty food and some excellent wine. It's not cheap, although - for the overall experience - we thought it was reasonably-priced.
If my partner and I return to Lyon, we will try to book Sylvie's apartment again as we agreed that it's the most attractive airbnb place we have stayed in, while Sylvie's great communications were reassuring and extremely helpful.
