Thumbs down on W service
If you want to feel unwelcome in a foreign city, this is the hotel where you should stay.
First, there is the check-in from hell. I was at first refused stay in this hotel because my room was paid for by Starwood points!!!! (That already defeats the purpose of collecting points for free stays by choosing Starwood hotels over other chains.) Check-in staff and in particular, one Nick Ivezaj, seem to have had their training in a military camp. Never have I encountered such unfriendly, arrogant and impolite staff.
Secondly, the standard of cleanliness leaves much to be desired. The hotel also runs out of toiletries, I believe, in a bid to make you purchase the full size products they have on sale in the bedroom.
Thirdly, it is a badly-lit hotel where you can hardly see anything, especially in the common areas. If you want to experience the feeling of staying in a bat cave, that's the place to go!
Lastly, but most importantly, I was charged incorrectly for meetings/conventions expenses, when I was there on holiday for the Easter break and certainly not on business. So beware of extra charges on your dedit/credit card statements when you get back home. It seems they will do anything to get extra money from you.
So avoid this hotel by all means when staying in New York. There are hundreds of other hotels which are much better.
