Pros:
Lots of space and good light. Larger rooms even for Harlem.
Cons:
When I lived there, the building had a mouse problem (living in the walls on every floor). There was a bed bug issue in the entire building as well for multiple months.
Also the building is poorly insulated, so it got very hot in the summer and very cold in the winter.
Advice to owner:
Invest more into this property and address the the fundamental issues.
