Loved this Hotel!!
Yes... it WAS an old YMCA, but not anymore!! It is a cool, trendy boutique hotel now. The rooms were small but were comfortable. The bathrooms were a good size. The hotel did have its shortcomings. We reserved a King room, only to find out when we checked in that the King rooms do not have bathtubs, which is a must for me. So we had to change to a room with 2 double beds, which was uncomfortable because the beds were too short and cramped for my husband and me. 
For business travelers... you'll be happy to know that there is NO SHORTAGE of electrical outlets!! There were 4 built into the top of the TV cabinet plus I saw 3 other easily assessable ones in the room that were not being used by lamps... & I didn't have to move furniture to find these.
We had internet during our stay, but in the evenings it didn't work very well, probably because usage was higher in the evening. It was annoying. Perhaps the hotel should get a few more routers or do something to improve internet service.
The service in this hotel was fantastic. Especially, the doormen and valets. I can't remember being in a hotel where they were so helpful and friendly. 
My biggest complaint is as SPG Gold Members, we were given ZERO recognition. We were not put on a high floor, as requested (we were on the 6th which is probably the lowest floor with guest rooms) and we were not put on the SPG Preferred Guest Floor. We were not given a room upgrade either, but of course, that is only when available and I was told that the hotel was sold out for at least one of the nights during our stay.
In spite of all my complaints, I actually loved this hotel. Every time I got off the elevator on our floor I felt I was on a New York City Street Movie Set. It was just amazing. When we come back... I'll be sure to request, in advance, a room with a bathtub (King room, if they actually have any) plus I'll be sure to ask for a room on the SPG floor. Perhaps, if I request early enough, they will honor my request.
