Pros:
Prime location (walking distance to Columbus Circle and Central Park), ease of access to multiple subway lines (A,C,E,1,B,D,F,M,N,Q,R,W), decent restaurants in Hell's Kitchen nearby, our street has a very residential feel away from the chaos of midtown (street is tree-line, and usually decorated with christmas lights in the fall / winter), building management and doormen are responsive (really like all of them)
Cons:
Near restaurants so there are some pests (no rats, but some roaches from time to time), flooring is old (wooden flooring subject to cracks and splinters)
Advice to owner:
See cons above
