Great property - but small rooms and poor soundproofing!
After staying at the St. Regis, our expectations were admittedly high. And for the most part, the Chatwal delivered, primarily with the room's excellent bathroom - an almost spa-like experience. The Asprey amenities are great, and the minibar was well-stocked and priced to be used. We had drinks and met a friend at the second-floor bar, a great spot for casual conversation. All around, the staff were friendly and went out of their way to meet our needs. For example, the room included complimentary garment pressing, steaming, shoe shining, etc., and the butler called to follow-up after we checked in, to see if we needed anything. 
A few negatives:
-We were in the basic room, and it was very small. There was little room to maneuver around the bed, and this seems more in line with the standard NYC hotel than a luxury hotel. Considering this place has nightly rates that can be $600 or more, I wouldn't expect even the smallest room to be this small.
-The bed was not the most comfortable. While the linens are very good, the bed here was a bit too firm for us.
A major problem:
-Noise control. In the bathroom, we could hear the conversation of those in the room above us. When I say "hear," I don't mean that I could hear muffled talking or whatever - little stuff like that wouldn't bother me. I mean I could hear every single word that was said, and it was more than a little awkward/uncomfortable. Now, usually I'm the first to say, "Why wouldn't you call and switch rooms?" to someone, but we had already gotten settled in, didn't have long before dinner, and didn't figure it would make a huge difference anyhow, so we left it alone.
Without the noise issue, this would have been 4 stars for sure (and perhaps 5 if the room size were more comfortable) - it is a dazzling property and a place I would happily stay at again, if I could be assured that the soundproofing were better.
