Smoker in the building. Putting this at the top because it was missed when I was booking this stay. Since we were there a week and had a few stay in, chill nights it was unexpected. So if you are sensitive you'll want to consider this. HOWEVER it didn't bother us too much and there were filters and fans to help. Aside from that we had a great stay. The apartment is very clean and cozy and the neighborhood is a favorite in NY.
