Julia is an excellent host who is very amenable and communicative; she was on vacation during our stay but made herself and a colleague available if there were issues. The apartment is in a great location, walking or metro distance from many Paris neighborhoods and landmarks. The main downside is the apartment is very small for two people, which we knew beforehand, but still surprised us. It was virtually impossible to do anything other than sleep. If you need a home base in Paris to drop your things and explore, this may be the right place for you, but if you need more of a place to hang out, I would not recommend it. Also, one of the keys to the building was broken and were locked out at 2:30 AM. Julia said she would talk to the building management after we checked out, so this may be fixed.
