When we arrived, the key was not in the specified location. Then, when I went downstairs to where the owner said he owned a store, I found the store was no longer there. Upon calling the owner through the Airbnb app, he was friendly and able to provide an emergency key that was in a nearby lock box.
The apartment itself was very clean. However, there was no toilet paper and we had to get our own. Towels were all still in the dryer rather than hung up. There were also a few broken chairs in the apartment.
The train is very very loud and runs all night. I have stayed in quite a few airbnbs in New York City I never heard a train this loud before.
