These are the pros: Shelley's place is wonderfully located. We walked from The MET the night before we left and it was not long. You're close to Central Park and three blocks from the subway with lots of shopping and food options nearby. There is a nice little terrace attached to the apartment that you can sit on if the weather is good (not sure where the cushions to the chairs were). It was quiet and I felt safe. Shelley seems kind and is communicative.
These are the Pros. The Cons are: You'll walk four flights of narrow stairs to get to the apartment. This was not a problem for us but it may be for some. Also keep in mind, as Shelley references in the description, subletting is apparently not permitted by her landlord (who lives on the first floor). While this is rampant in NYC, this added a layer of anxiety to our stay that I should have anticipated. I will be re-thinking AirBnBs hosted by renters in the future.
