Nice, but needs improvement
I had high hopes for this hotel as I am familiar with the Indigo brand. I have stayed in several other "sliver" hotels in the area (Hilton Garden Inn, Doubletree Chelsea, Holiday Inn 6th Avenue), and there really wasn't that much different about this hotel. I had a corner room on a high floor which was the about the same size as the rooms in the other properties. As Priority Platinum ambassador, i was hoping for an upgrade to a suite, but none was available. 
On the plus side, the bed was very comfortable, the Aveda toiletries were nice, there was an in-room safe to accommodate a laptop and a minibar in the room. There was a bathrobe, but slippers would have been nice as there are wooden floors in the room. The bathroom size was decent, but the toilet needs to be fixed (the lever kept getting stuck) and there were signs of mold in the shower grout.
There is a hotel restaurant which has a decent menu, but I did not eat there. What was kind of frustrating was the very small gym. There are two treadmills, one of which was not working and the other which was being used for over an hour by another guest, so I was not able to work out. This was probably the most frustrating. The business center consists of two computers in a cramped environment.
I would stay here again if the rates were comparable to the other hotels I listed above, but I would not pay a premium as the amenities do not justify the usual rack rate at this property.
