Nick Jonas -- I'm Livin' Like JP Morgan!!!

Nick Jonas is hosting a XMAS holiday for his brothers, at the reasonable price of $7,500 a night.

Nick hooked up with airbnb to snag JP Morgan's carriage house in NYC for the week between XMAS and New Years.

The 1920 house is amazing ... 5 bedrooms and a matching # of bathrooms, all on 3 floors. It has an indoor pool, theater, and wine storage room.

Some of the rooms have the original barn doors.

BTW ... the Christmas tree was not included. The Jonas brood brought and decorated their own.
