Not a 4* Hotel, Tourist Location
Stayed with Crowne Plaza for 7 nights in June. Booking was made in April, we booked a room for 3 girls and the hotel assured us that they had rooms to facilitate 3 people. The only request we had made was to have a twin, which in America is 2 double beds.
After waiting 15 minutes to check-in, we were assisted by a totally rude young girl. Constantly rolling her eyes at her computer, not a single smile or any effort to welcome us. Though, I think it's worth adding that the girl next to her seemed very pleasant and made a genuine effort to welcome guests. We just got unlucky!
The room we got given had a King Size bed. Wasn't ideal at all. Called room service/concierge to see if we could change - the answer was no. Had to call again to advise that we required another towel, no towel was brought up! Resorted to writing messages to the house keeper for an extra towel, still didn't get one. Ending up where I was calling them nearly every day. 2-3 times to ensure we got three clean towels.
The room itself was modern, reasonably clean but with a lousy bathroom. 3* standard at best. The rest of staff such as the concierge, doormen etc were pleasant.
The location is extremely touristy, very central an ideal for people making short trips to the city. I personally, will never stay on Times Square again as it is too busy and I felt that we ended up taking Times Square, such a fantastic tourist location, for granted. The first time I went to NY I stayed in a Midtown East hotel, which I felt was a much better location (and Hotel!)
1* for service, 3* for ameneities, 3* location. 
I will not return to this hotel again! They really need to work on their customer service skills and working efficiently!
