Both the building and the apartment itself are pretty cool and charming. Walking up the stone steps is a fun workout and really makes you feel like you're in a historical setting. I like the open and minimalist feel of the loft although the decor was severely lacking. Obviously for an Airbnb like this I don't expect much in that department but the walls are completely bare and we felt like the aesthetic bordered more on "warehouse" than loft in places.
The kitchen has tons of space and enough basic supplies to do the job. I will say a couple of the pictures seem embellished -- which is to be expected -- but a couple were a little more misleading like one of them showing a stand mixer and a clothing rack which weren't there.
The "fully equipped" amenities were a bit lacking as well. We didn't see any toiletries and we were given just one bath towel each and nothing else. I asked if there were any hand towels, wash cloths, etc and was told "no, sorry" so we spent a decent amount of time shaking our hands dry after washing them or the dishes.
I suppose the location is technically pretty good but some of the reviews are really overstating it imo. The very immediate area (within 2-3 blocks) is completely empty and getting to the nearby busy areas takes longer than you think because of the hills/stairs involved. There was also a lot of construction going on at the corner which contributed to the empty feel right around the apartment. It's a 10 min walk uphill to the Blvd de la Croix Rousse (where the market is), a 5 min walk down the stairs to a small cluster of cafes, a ~10 min walk to the Hotel de Ville and metro and 20-25 mins to the downtown and restaurant hot spots in the 5th arr. Scooters are one of the best options but it's also a little deceptive as you have to weave your way slowly down the hill and for some reason you can't park near the apartment so you need to park at the bottom and walk up. Like I said, the location is OK but I found for practical purposes it wasn't the best.
