Le Chapitre is the place i stayed for 2 weeks when i was in lyon for a conference. Host was very kind. The apartment is in third floor, no lift. Got access to laundry and ironing. If you want to cook, you've got facilities to do so.
This trip in June for me was surprisingly warm in lyon, it was hot in evening, but our host was kind enough to provide pedestal fan for us. Entry for the common entrance was with keys only, with three friends staying together, we had to co ordinate our schedule to get entry. But now they have installed electronic entry.
I would recommend this apartment for those who stay out during day, as there is a school next door, quite noisy in school hours. On the other hand access to metro and main railway station is walking distance 10 mins. Variety of restaurants in walking distance.
