Great boutique hotel!
LOVE this hotel. I'm staying here now, with my husband and 4.5 year old daughter. We love the ambiance and the decoration. For those reviewers who called it the Gramercy "Dark" hotel, the mood lighting is very evocative. Yes, it's on the dark side, but you can always turn on a light or open the blinds to let in the light.
We've found the staff here very pleasant, especially the Gramercy Tavern employees. Austin, one of the concierges, was extremely helpful in terms of restaurant recommendations and reservations. The doorman is super-friendly, and very nice. 
The terrace restaurant is beautiful, and again, the staff is wonderful. Every morning they greet us with a "Hi, nice to see you again" and remembered our preferences, which is service I haven't even gotten when staying at the Penninsula or Four Seasons. 
The gym is good, with a lot of free weights, which is unusual in a hotel gym. 
Yes, the bar is full of very fab people (at least fabulously dressed... well, some of them), but coming from L.A., we find that kind of amusing. The scene doesn't intrude into the lobby, and didn't have any impact on us in terms of getting to or from our room.
If you want to stay in a boutique hotel in the Village/Flatiron/Gramercy area, this is a terrific hotel with a fun vibe, very funky/elegant, with friendly staff.
