The location of the apartment is its best attribute. One block off of Montparnasse Blvd. and around the corner from the Vavin Metro, you are surrounded by numerous restaurants, cafes, boulangeries, patisseries, etc. We never met Kat, communicating instead by email. We did not receive explicit direction beforehand on how to access the apartment, and when we arrived at the address, we waited outside for a few minutes for someone to meet us. Once someone in the building let us into the foyer, we looked for Kat's last name to be buzzed up, but no one was in the apt. We waited another 20 mins. and then noticed there was another resident with the same last name. We tried that apt. and got Kat's son, who lives in the apt. across from the Airbnb and he buzzed us up. After figuring out that the correct stairwell was through the courtyard, we climbed up the 4 flights. The stairwell was being renovated and repainted, so guests should be sure not to touch the walls lest you get get drywall and paint dust on your clothes/luggage. The apt. itself is functional with the basics covered. The bed is full-size, probably fine for a couple, but my sister and I decided to sleep separately and there is a thin mattress you can put on the floor for use as a second bed. We slept comfortably until the workmen started banging and hammering and sanding at 6am and 6:30am respectively on the two weekday mornings we were there.
