We were 4 (me, wife + parents) on this trip to NYC. The location was great, only a block away from subway 2 and 3, and less than 10 minutes away from other subway lines.
In less than 15 minutes you can walk to central park. Entering and leaving the apartment was easy, even though we landed late in EWR, the keys were waiting for us and communication was perfect throughout the entire process: from reservation to leaving the place.
When we come back to NYC, we'll definitely think about this place!
