Nice host.
As other reviews have mentioned, there is an indoor door separating two airbnbs. Other airbnb guests will be staying above you and you will be able to hear each other. I solved this problem by piling up all the extra linens at the top of the stairs.
Also, when you have food delivered they will always try to deliver it to the upstairs airbnb instead of your door. It helps to put a sign in the window to help the delivery people out.
When I arrived I was confused about which apartment it was. Expect a front entrance to the basement. Beware of google maps changing the address on you.
