If you haven't tried this side of the Waldorf, you don't know what you're missing
I have stayed in most of the nice hotels in NYC except, until this week, The Waldorf Towers. The Towers has a well-known illustrious history, from Presidents to Kings to Mrs Douglas MacArthur. One's perception of the Towers may be that of a past its prime, dowager of a hotel. Well you would definitely be wrong. The hotel and rooms, while very last century in style (I don't mean that negatively, but rather as in very elegant) are in excellent condition and spacious. The high ceilings and uncrowded common areas give you the sense of being cosseted in a private cove in a very busy city. It feels very much like you are in the comfortable quiet confines of a pre-war Park Avenue apartment (which you are). The separate entrance sets the tone, and it doesn't stop. The exclusiveness of the Towers and the relationship with the employees feels more like a co-op residence rather than a hotel guest experience.
Now, while there are a few hotels that offer this level of luxury - the Carlyle, the Pierre, the St. Regis, etc. what I like about the Towers is that you also have all the features and services of a large hotel just a few yards away in the main hotel. Also, the location - just a couple blocks north of Grand Central - is really ideal. 
I will definitely make the Towers my first choice of NYC hotel going forward
