Convenient location near the metro, short walk to Trocadero with a great view of the Eiffel, and a 15-minute walk from Champs-Élysées. The area felt safe and quiet at night.
The building has an elevator. The studio was relatively clean and spacious. Celine wasn't aware that a few things were missing or needed maintenance (ex: no detergent, clogged soap dispenser, broken clothes drying rack, strips of wood protruding from the floor) but resolved them quickly after I told her. There's a washer but no dryer so you'd have to air dry or use a hair dryer in a pinch like I did. Take quick showers because the water goes cold quickly.
Celine lives across from the studio so it was easy to communicate with her. She responded to messages within 24 hours. She was friendly and helpful during my stay.
