Marie has a lovely apartment steps away from the Place des Terreaux, the Opera, and the Hotel de Ville. The advantages of her apartment significantly outweigh the few drawbacks.
Marie is a gracious host and an excellent communicator. I had a personal problem while there and she did everything she could to help going well beyond what might normally be offered.
Her unit, as shown in the photos, is decorated with an artistic flair. She has ample kitchen equipment and utensils available and importantly there is a washing machine in the apartment. The rooms are spacious and there is good air circulation. The bathroom is well-designed with a deep tub but be aware that there is not a shower per se. There is however good water pressure and lots of hot water.
The bed is firm but also yielding and not therefore hard. Both sets of bedroom windows are outfitted with interior shutters that close off light and most sound from the outside.
Regarding sound her apartment is mostly quiet as advertised. There is however a large church carillon tower that chimes the hour from 0700 - 2100 daily. Also, there is one apartment across and two floors down in a neighboring building where 20 somethings live and whose voices are clearly audible when the windows are open along with the music they play. They are not at home of course all the time.
Lyon can get hot in the summer and Marie's apartment is not air-conditioned. She does have a fan that can be used in both the LR and bedroom which moves the air quite efficiently. There is of course heat in the winter.
Marie's apartment is in a building dating to 1900 on a small pedestrian street. Note that the building does not have an elevator and Marie's apartment is on the 4th (American 5th) floor. There are double flights of stairs leading to each floor so for people with disabilities or infirmities the stairs could prove a serious challenge.
But, once again, the few drawbacks noted above should not normally prove impediments to rental of what is a very comfortable and spacious apartment.
