We enjoyed our stay in Eric's place due to its location, layout, and size.
The kitchen is well equipped with everything you would need to enjoy meals at home if you tired of dining out, and the living room, with two lounge areas, and a dining table for 6, gave ample room for relaxation.
Located within an easy two minute stroll to Place Thereaux, and a five minute walk to the old town in the other direction, all the key sites of Lyon are within easy walking distance.
As other guests have mentioned, on Friday and Saturday nights it can get noisy in the area, even 5 floors up, but we had no issues on any other of the five nights we were there.
The only downside for us was that there is was no free parking nearby. There are two parking stations very close by however, Thereaux, and Opera, that charge similar hourly rates. We chose Thereaux and ended up paying 154 euros for five days, as we did not take the car out the entire time we were in Lyon.
Eric was a great host, communicating freely with us during the whole process from the time we booked right up until when we left. He gave us a list of places to eat, things to do, and a list of must sees.
Overall Eric's apartment is a great place to stay in Lyon.
