"To assume that a new poster is a broker scamming to push units is very pessimistic. I assume these discussion boards go to better use than that!"
Well, then it is obvious that you did just find out about this site.
As I mentioned, it happens often here: posters coming in on their very first posts trying to promote apartments or their websites or whatever.
Understand that posters here are on high-alert and thus Midtown's reaction. You should not take it so personally.
Now on to the Centurion:
While I like this building, it is unfortunate that it will have "highly reflective" glass as you say. If so, mirrored glass is usually down-market looking and would be wrong for this block. And mirrored glass combined with limestone sounds pretty dreadful.
Interesting that Pei feels that tenenants "would never tolerate retail space in an ultra-chic condo building". They do at 15CPW, the Time Warner, Trump Tower, The Olympic Tower, The Plaza etc and etc.
Pei might want an attended garage.... but is he aware that a garage entrance on such a side street only ruins the ambience for the rest of us?
