Excellent location, clean room, front desk and concierge staff were efficient and helpful. We stayed on the 6th floor. In the morning, our room smelled as if someone was cooking a greasy breakfast outside our door. At 8:45 a.m., a maid knocked and then proceeded to come in. No apology. Just, "When are you leaving?"
The Westin could do a better job insulating rooms from noise. We were, of course, on 42nd Street, but I've stayed in other hotels in midtown with much better soundproofing.
