3.5 Stars: A Perfectly Fine If Not Particularly Special Hotel
I recently spent two days at the Parker on business. A few quick notes:
1. It has a great mid-town location (though so do a number of other hotels).
2. The room was fine, clean and comfortable. 
3. The small bar area is a nice place to have a drink if you can manage to swing one of the seats.
No real negatives, just nothing particularly special about the hotel to set it apart. Its actually somewhat colorless - though in fairness, a Monday-Wednesday stay isn't exactly the time of the week most hotels show their charm. 
So, depending on what type of pricing you can get, it may be a perfect place for you to stay on your trip..
