Overall I would summarize that my 3 nights in Paris were great, not only because of the great accommodation, but also the warmth and kindness of my host, Lo.
Although it was just me traveling, the apartment would be quite comfortable for two. Compared to some of the pricier hotels I had stayed at in previous trips, the apartment is quite reasonably sized, and I really enjoyed having separate bedroom, kitchen and bathroom, as well as sitting room. There walk up to 2nd floor was not a problem for me, and the Airbnb listing contained no surprises.
I was quite pleased that Lo was able to meet me a little earlier than usual, and had a nice assortment of beverages, bread and fruit when I arrived. The grocery store is only 5 minutes away, and was good to get anything else I needed.
The apartment was quite quiet, as it's located in a quiet residential area, about 5-8 minutes from a really great park, Buttes Chaumont. Be sure to spend an hour or more in the park, it's a nice treasure.
Anyhow I am rambling on, but you get the picture. It felt like a home away from home, and I was able to relax and enjoy my stay.
