Pros:
Well maintained building and apartments, rent stabilized units, good options for broadband, nice courtyard in back. Super lives in building, management is very responsive to service requests. Fairly priced laundry in building. Quiet block, close to good grocery stores and subway. I could see myself living here for years.
Cons:
Elevator is slow and breaks frequently. No bike storage or storage room. (But there are plans to add a bike storage shed in the courtyard.)
Advice to owner:
Keep doing what you're doing.
