I landed a few hours before check-in and was able to store my luggage in the apartment until it was ready. Stephanie's husband graciously carried my luggage up the stairs and gave me a run down of the apartment, which has a lot of amenities. The building itself is quite beautiful and is located on a quiet street walking distance from some of my favorite places in the marais.
Their cleaner comes once a week, so the apartment was very clean; linens and towels were swapped out. The washer and dryer are very easy to use compared to others I've come across while in Paris, and overall the stay was very comfortable. I'd recommend 10/10 and will likely request another stay in the near future.
