Olivier's apartment is simple and cozy, and in a great location. It is within a ~10 min walk to the major Chatelet Les Halles metro station and with restaurants in the vicinity. It is on the 5th floor without an elevator, which is a bit of a climb with bags, but Olivier helped us carry our luggage up, which was great. He is also very responsive to messages, and gave some good local tips. Overall, a good place.
