Great location but very disappointing customer service
I stayed at the Crowne Plaza Time Square for 12 nights.
Firstly, the good - great location right on Broadway at Time Square. My room, a corner room, was large and reasonably clean though had maintenance issues (see below). I had a view of the Hudson River, which was nice, but nothing spectacular (and this was from the 20 something floor).
I had a number of issues with my room and service however, which while individually were small issues, together I felt really let the hotel down, especially considering this is supposed to be '4 star' property. 
After waiting until after 3pm and then being checked by some staff that weren't particularly friendly or welcoming, I headed to my room for a shower but found that the shower in my room was clogged and started filling with water when I tried to use it. Hotel maintenance had to come and dismantle the drain and pulled out whatever was stuck in it, which took around an hour or so. Then, I discovered the toilet was clogged. Maintenance again had to come and attend to the issue; and took three visits over as many days to fix the problem permanently. All in all, this was quite inconvenient and annoying and I never really received a proper apology for the inconvenience.
A few days after this, I came to to my room and found the card wouldn't open the door. Back downstairs to the front desk, I was given new room keys, apparently it seemed that on check in they had programmed the keys to stop on working a week earlier than I was checking out. A minor inconvenience but still a bit of an annoyance.
Room service at the hotel ends at midnight. One night I called just before 11pm, my order was taken and I was told it would be 45 minutes; however it never arrived. By the time I realised it was getting a bit late and called back, it was just after midnight. No answer. I called the front desk and was told they were very sorry but it appeared the kitchen was closed and everyone had left and they didn't know what had happened to my order.
Having been on a 7 week visit to the US, staying at 9 different hotel across the country ranging from 2 star to 4 1/2 star; this "4 star" hotel had the worst service of the lot.
I should also mention, internet is quite expensive - over the 12 nights I was there, it cost almost $100.
Finally, a few days after my stay I received a generic email that hotels send out asking for feedback, which I provided explaining all the issues. I still never heard back from Crowne Plaza. I assume they just don't care.
With thousands of hotels in Manhattan, and hundreds around Time Square, there are plenty of other choices before staying at the Crowne Plaza Time Square and I suggest looking elsewhere.
