The apartment was exactly how it was advertised online. Check in was easy. You just needed to pick up the keys in a lockbox at a location 2 doors down. The apartment was on the first floor and that was very convenient. Having only one toilet (located in the hallway) seemed like it might be a challenge for our family of 4, but the fact that each room had its own shower and sink made it work just fine. Beds were comfortable in the two rooms, but we didn't sleep on the pullout couch, so I can't comment on that.
We were a 5 min walk to the Arc de Triomphe/Champs Elysees and a 15 min walk to the Eiffel Tower, so it was convenient to touristy areas. However, it was about a 25 min walk to Rue Cler (one of the most famous market streets in Paris), and we had a hard time finding any kind of "market" near the apartment. However, there were 2 grocery stores within 2 blocks.
Patricia was a wonderful host. She was great with communication and was flexible with allowing us an early check in as soon as the cleaning person was finished. She also helped reserve us a van to get us to the train station early on the day of departure (I was having a hard time reserving one and was hesitant to book one if I wasn't familiar with the company). She paid for the van and allowed me to leave cash for her. She was very hospitable!
