50 Gramercy Park consists of very large apartments (2-4 bedrooms that are over 1800 SF) so it's probably not the right building for you. Are you interested in buying or renting?
That building is made up of 2, 3, 4 bedroom apartments. So right now there are no 1 bedroom apartments available. Are you looking for a one bedroom apartment that faces Gramercy Park? Are you looking to rent or buy? I can email you the available apartments that fit your criteria. Feel free to send me an email at firstname.lastname@example.org
