Stephanie’s place was great for us as we had an early train from gare de Lyon in the morning. Everything worked well. We communicated via google translate and it was fine. We didn’t know but the key to the apartment works at the second door in the entrance. I don’t think it’s the same lock, just part of the key also works for it, I think. In any case, we were worried when we came back and Stephanie had left the apartment that we wouldn’t be able to get back in but it was fine!
