Tl;dr: Apartment is great, the company running it is so so.
The apartment is just how it’s pictured - really cozy, cool loft bed, stocked kitchen. The washer/dryer unit is in the closet on the stairs that’s across the apartment main door (it took us a second to find it).
The location is amazing! It’s 10-15 min walk to the louvre and there are a ton of great restaurants, stores, etc in the neighborhood.
The downside was the check in. They have a person hand delivering the keys and the company sends you their number to link up. Our person ended up being close to an hour late for the time we had scheduled. When we got in, the second bed wasn’t set up which we also requested, the trash was full. Checkout instructions were also not super clear; I tried to clarify but didn’t get a response.
