Stayed at this property on spring break (Mar 2017) with wife and 18 year old daughter:
Host - Patricia was very easy to work with. She proactively reached out to me every day and was patient with me as I struggled to coordinate arrival due to jet lag.
Location: In 8th district near Champs Elysees, so walkable to shopping and high end restaurants. Safe neighborhood, but busy street is noisy at night. Used Uber, so not really sure how close to public transportation.
Cleanliness: The apartment was extremely clean and well maintained. Everything (appliances, plumbing, HVAC) worked. Photos are accurate, but it is a pretty small living space.
Amenities: Provided towels, shower gel, coffee, etc.
Summary: Very nice apartment and host. Value of location is dependent on your itinerary while in Paris.
