Yas was very nice, and we could leave our luggage in the apartment even before check-in as she hadn’t finished cleaning. When we returned, however, the flat was not clean. Especially the rugs etc looked like they hadn’t been washed for a while, so did the steep staircase.
The flat extremely tiny and carelessly put together (e.g., all cleaning equipment etc standing around). We could not stand straight in the shower. Also, it smelled like chlorine which didn’t disappear after opening the windows for a while. The flat is underneath a staircase on the ground floor so it is very loud. The bed is very hard, but large enough for two people.
Overall, it is an ok place to stay close to two major train stations in Paris for a night, but sadly not more.
