We enjoyed staying at this loft. The views are in fact beautiful. When we booked this we knew what we were signing up for, which was 7 flights of stairs, so that was a little tough but again we were fully aware :)
Since we hadn't seen a specific check-in time we emailed Line the day before on our ETA but turns out we couldn't check in until 5pm. That wasn't ideal as we were arriving to Lyon earlier that afternoon, but in order to accommodate this Line and Walid offered to watch our bags, which was nice.
The place was very charming and well kept and we loved using Line's books. The only thing would be that the bath towels still smelled a little of cigarette smoke, but we were told when we checked in that the visitors before us has made a mess and it was a disaster that the cleaning services were restoring/cleaning the whole day for, so we didn't wig out on this. All in all, great location (we walked everywhere except the metro to the airport shuttle), and gorgeous views.
