Annette's apartment would be perfect for a couple during a brief stay in Paris. Annette and her husband were very hospitable, and I appreciated the local recommendations and amenities (bottle of wine, coffee, tea, etc.) provided. The location was wonderful; there are plenty of delicious restaurants, cute markets, and cool landmarks to visit within walking distance. The metro is nearby, and it is relatively cheap and easy to get an Uber across the city if you don't want to walk.
My partner and I spent six nights in this Airbnb, and it was much too small for that amount of time. This was our first trip to Europe, so we'll keep this in mind for the future. For some reason, we weren't fully able to relax in this Airbnb. I'm not sure if it was due to the tiny space, or the fact that we were overcoming a cold during the entire trip. The apartment is an older building, so noises from other tenants and outside sources were loud and kept us up a few nights.
