Apartment was clean and spacious for a city center location. It is within walking distance to many major tourist attractions. While it is located on a busy street, it is in the back of the building and shielded from street noises. The double gate entrance is very secured. The shower is exceptionally spacious and has excellent water pressure for an older building. It is an older building and the footsteps from upstairs into late night/early morning hours were heard. We were not bothered. If you are a light sleeper, this might be an issue.
Overall, we enjoyed our stay. Owner was responsive. It is a keeper for next visit to Paris!
