First of all, Julia is a very sweet person. She waited for us to arrive until almost midnight on a week day. Communication was always good and fast. Her apartment is in a great location, in a nice neighborhood, very close to the metro station. The room was clean, as the rest of the place, and big enough for two people with lots of baggage.
Also, I really enjoyed the conversations we had :)
I recommend staying at her place if you visit Lyon!
