Location, location, location! After many trips to NYC over the past three decades, I finally escaped Midtown and decided to stay in Lower Manhattan. So glad I did. It's a much more interesting part of town, and Kat's apartment couldn't be more conveniently situated right on the L train line and within walking distance of multiple neighborhoods. I lucked out with good weather (for December!) and spent a lot of time exploring.
Another great thing about Kat's apartment is the relative quiet in spite of its location on E. 14th. The windows face the interior of the block, so you don't get that much street noise aside from an occasional siren. I was able to sleep in with no problem. The bed was very comfortable and the entire unit was well-heated.
Kat was very responsive with check-in and check-out. I didn't have any reason to contact her during my stay but am sure she would have been helpful.
