Booking was easy and Marie was responsive with questions both before and during our visit. She met us at arrival and even helped carry one of our bags up those many steps we read about. We are a family with teenagers, so the steps really weren't a problem for us. The apartment was charming with great views over the rooftops and even the tip of the Eiffel Tower. The main area was spacious, though the bathrooms are small. The washer/dryer were very useful and the large double tub was very relaxing after walking around Paris all day, as we did. The location is perfect - we never used the Metro once bc we could walk to everywhere (except to Versailles we took the RER, and once the bus from Trocadero). The upstairs has a loft with bed and skylights, the main floor bedroom has a mattress on the floor, lovely views and ensuite bathroom with double tub, washer and dryer and many storage closets. There is also a toilet with sink and shower in a small bathroom on the main floor. If you like museums, we recommend the Paris Museum Pass. Another recommendation is a boat ride on the Seine from the Tour Eiffel area. Marie also advised us on what time to leave for the Orly airport. If you don't mind a little exercise up steps to the apartment, the location is central, and the place ideal for a family that needs space to relax, two bathrooms and a washer/dryer.
