My question involves landlord-tenant law in the State of: NY

Hi everyone,

My question is simple,
When I rented my place in Washington Heights in NYC, the realtor said the building has a laundry room.
3 months ago, the laundry room was discontinued, and the building no longer has one.

Since I was promised a laundry room when I signed the lease and there isn't one present for the past 3 months, do I deserve a remission in the rent? If so, how much should I ask?

Thank you all very much for your help.

Michael
