Just stayed a week in Justin's apartment, and it was perfect.
The place looks exactly like in the photos. The location is great, right in the center of Paris, next to the Pompidou museum.
Justin was very helpful with every question we had and provided all the information you need to get your vacation started.
The second floor may be a bit short for tall people but we didn't really feel that it was an issue.
My girlfriend and I will gladly return for another visit.
