Great NYC Location! It's Pricey, though!
I stayed at the Essex House with my wife ona business trip. The location at the southern end of Central Park is fantastic! It is a perfect place to start a walk in the Park.
The hotel is transitioning to a JW within the Marriott brand. That led to some issues, but they were really minor. However, if you are a Marriott Rewards member, this may cause you some issues too.
The rooms are clean, but very small (as is often the case with older hotels). Views can be awesome, but some are into a brick wall (so don't be disappointed).
Overall, a very nice spot, but I am not sure it is worth the price.
