I too stayed here last Sunday night - had a worldwide corporate rate of $170 which was much less that the Times Sq or Lex Hyatts that I stay at.
As stated above, rooms are quite small - would only work for 1 or max 2 people. Bathroom is very small with no counter space to put one's toiletries. No enclosed closet which was ok. My room had an iron but no ironing board - must have been teething problems. Room had a small sofa - good for 1. One potential negative for me was that there didn't seem to be much of a desk to work on - just a very small area that I wasn't sure would work.
At check in - was told I could have diamond breakfast in the restaurant but no mention of the diamond amenity. Regardless, the 1k points posted.
Looking to the latter part of Nov, some of the rates here are quite good - almost half of the TS or Lex - so will look to stay here again and same my client money.
