Nice, but I think it's overrated
Let me begin with few positives: 
1. The staff, for the most part, is fantastic. The bellmen and doormen and drivers are so nice, and the front desk staff goes out of its way to be accommodating. 
2. The courtesy car IS extremely nice, and it was available several times when we needed it. 
3. The location is great.
Now, let me explain what failed to live up to these other standards. When you are charging $400+ for your rooms, you have to maintain them perfectly. There were nicks and dings on all of the furniture. The paint on the mirrors was chipped, and the walls were scratched. That's just a major turnoff for me. Now, those mishaps may have occurred because the rooms are so SMALL. We had a deluxe room of some sort, and it was teensy-tiny. We could barely fit all of our luggage; plus, there was very little storage to unpack (something I always do when I stay for more than 3 nights). Additionally, we felt pretty inconvenienced when both elevators went out one night, and we had to walk up the 8 flights of stairs to our room. Thankfully, we're pretty athletic and young, so it didn't inconvenience us too terribly. Finally, we felt that the evening concierge was lacking, but the hotel has already done its best to fix this problem, so I won't go into detail - especially since the female concierges in the morning were so excellent. 
Next week, we'll be trying out another hotel in Boston, and we'll definitely write a review. Perhaps I am being too choosy, but we stay in great hotels all over the world. I feel qualified to pick a bone or two.
