Julien's apartment is great...it's in a great location (right by the Eiffel Tower so it's easy to find when exploring Paris) right by a ton of public transit options. The terrace is great and we had many drinks and snacks while people-watching. It's a 2nd floor walk up (3rd floor for Americans) but totally doable, with an elevator for luggage. We felt very safe with the security in the building.
