We enjoyed our stay at Amy's apartment for a number of reasons (and we would definitely stay at Amy's if we are in New York again).
The first being the location and it's proximity to Central Park (literally 3 mins away) and also to shops and local restaurants/eateries.
The second would be that Amy's apartment is quite large by New York standards, and it is a 2 bed and 2 bath unit, which is difficult to come by. As such the 4 of us were quite comfortable without feeling cramped as we had our own space.
We also liked the fact that we had access to a garden from the main bedroom.
However there are a few things to note.
Sound proofing is quite bad and you can hear the upstairs neighbour walking / moving about quite a lot as they have small children that are constantly running around. We didn't mind it but if you are a light sleeper or like peace and quiet then this could be a problem.
On a few weekends, another neighbour played really loud music throughout the weekend which again could be annoying. But as we were on holiday mode and quite chilled it didn't bother us.
The apartment is spread over two floors, ground floor and a basement level. The washing machine and dryer is in the basement as is the second bedroom.
The basement can be quite cold and also there are no windows and therefore no natural light in the basement.
