This is a very clean, cute apartment in the heart of Lyon. You're steps away from Rue de la Republique and quite close to all the restaurants, bars, shops, and attractions. I returned late at night twice and both times felt surrounded by locals and tourists having fun, and felt very safe.
At the entrance to the apartment, you go down a very dark hallway, and up several flights of narrow dark spiral stairs. For Americans, this may be different than what you're used to. Those with physical disabilities may struggle. Also if you think you might indulge in too much to drink, these stairs could be quite unwieldy. I admit, I also found the dark hallway a little creepy when coming back alone late a night.
Additionally, the window AC unit was not easy to figure out. It's a self check in, so there's no-one to show you how to use it. I tried to use it multiple times to no avail... Not entirely sure if it works, or if it's just that I couldn't understand the instructions.
