My wife and I stayed at Jean-Jacques apartment for 4 nights. It is in the perfect location for exploring Paris, as the metro is right across the street. We loved being able to walk to the Eiffel tower and enjoyed walking along the Seine River each evening. We felt very safe everywhere we walked.
There is a grocery store right down the street, as well as many cafes and restaurants within walking distance.
The apartment is small, but big enough for two people. Loved the view of the Eiffel Tower from the small window!
