Very disappointed, room request not honoured and hotel was tired
The hotel is in a great location and was easy to get around and the anytime anywhere concierge service was handy during our stay. I regret to say that I doubt I'll be staying in a W again, especially given I'm a consultant who spends lots of time in hotels and am a Starwood Hotels fan. I paid my own money for two rooms to stay in a W on this special occasion in NYC; it definitely wasn't worth it.
I booked in October/early November for a trip in late January 2012. I was staying for two special occasions, my 30th birthday and my mother's 60th birthday. I requested 2 king size bedrooms on the same floor. Here are some observations and reflections from our stay (Jan 25 - Jan 31 2012):
1. When we arrived they tried to put us in a double rooms with no compensation
2. Made no reference to my request for two rooms on the same floor - when i brought it up they said a large party decided to extend last minute and couldn't honour it, they told me to try the following day, when i went back the following day they said not to bother as there was construction and we'd be bothered by the noise. Again no apologies that they couldn't do anything to help us
3. Two friends sent cards to the hotel with our names and the dates of our stays on them scheduled to arrive for the start of the stay, we were not advised of any cards or mail arriving at the hotel for our attention. Given two friends sent cards, I believe the hotel let us down, rather than the US Postal Service but obviously impossible to know for sure
4. The room keys were deactivated every time you put them in the lift to access the room floors. We had to keep one for the lift and the other for the room which meant we each needed to carry around 2 keys! We had to have our room keys reset several times, I mentioned something to the hotel; they sent someone up to reset our room lock, but this was to no avail. They did remove some charges from our room which was nice and appreciated. 
5. On checkout on Jan 31st the woman serving us was unpleasant, inaccurate and rude when we enquired if our credit card had been charged for the additional items on the rooms. Not the service I expect from a W hotel. 
6. The overall standard of the hotel rooms has declined, the bathroom was looking tired with brown mould in the shower. There was a champagne cork on the floor in the room when we arrived indicating the level of cleaning could use improvement, and our rooms were inconstantly refreshed with toiletries and bathrobes during our stay. 
7. I wrote a feedback note at the hotel when we left, no one has contacted me regarding my stay. Such a simple thing to do!
