Pros:
Overall, the building delivers great service for the price of the apartments. I wouldn't put this in absolute "luxury" category, but given pricing in NYC the monthly rent doesn't fit that either. Pros are: no bugs, no rodents, can't hear your neighbors, great views, remodeled apartments, clean hallways and lobby, and generally attentive staff.
Cons:
Pros definitely outweigh cons, but the street is not my favorite and neighboring buildings do not maintain trash or sidewalks. Also, the elevators have gone down which is troublesome for a building of this size.
Advice to owner:
Invest in an elevator overhaul and figure out a way to integrate lincoln center street cleaning on 60th st. Keep up the good work with apartment maintenance and tenant communication.
