Jhon's place was a perfect space for my mom and I when we visited NYC for a weekend trip. It was very clean and organized. It's about three blocks away from Central Park.. perfect walking distance! Also, half a block away from the nearest public transit if you'd like to go somewhere further away.
Jhon was also kind enough to order breakfast for us one day, and was very helpful/ always checked in to make sure we were fully comfortable.
Overall, highly recommend Jhon's place!
