Location is perfect for a trip in Paris (substation is close, great restaurants etc. nearby), it was clean, we slept very well (very quiet & comfortable bed), received helpful information & great tips (e.g. restaurants) via PDF and it was kind that guests are allowed to use shampoo/coffee. The check-in time was a bit unflexible but as Stéphanie is starting with Airbnb we assume this will be improved.
We absolutely recommend that place!
