Margaux' apartment is an 18 minute walk from Montparnasse Train Station and Catacombs are just a stone's throw away. Even though Margaux was not there to greet us, she made sure one of her friends was able to welcome us at her apartment. We also enjoyed conversing with her tenant, who was there to offer advice/helpful tips. The apartment itself is very small, but cozy. We found the bathroom to be on the smaller size. Just a few things to note: bed linens and towels are not provided and the apartment is on the 5th floor with no lift(elevator) in the building. After a days worth of sightseeing it can become burdensome. There is no central air/fan in the room but overall it was a good value for money.
