After flying into Frankfurt, we had booked a train to Paris which would have arrived at 17:00. Due to track construction, our train was delayed 8 hours. We arrived at the Airbnb at 21:45. Thankfully, we had code access to all the doors. That was wonderful!
You will need to carry your luggage up 2 flights of stairs to reach the apartment.
We were there only one night, but we were very grateful for the clean, quiet apartment.
