The apt is 10-15 from Lyon Station. Very old building, some parts need refurbishment, but the apt itself is well renovated.
But what I think to make this stay has excellent value of money is Penelope herself. Once the reservation is completed, she sent a complete information about the apt, which I found very helpful. (I've been using Airbnb for quite sometime, believe me, there are hosts that never bother to provide further info apart from what they wrote in Airbnb desc). And Penelope is quick in answering message, quick to response to inquiry. And on the check in day, she spared some time to explain bits and pieces about Paris sightseeing.
