I'll echo the previous comments about the beauty & luxury of the resort both inside and out. It's a great location for a getaway from DC.
The rooms are spacious and very well appointed, however, there is a major drawback. As noted by a recent commenter, our room had very thin walls and we heard everything in the next room late into the night. In our case, it happened to be teenage kids arguing and cursing (I hear them clear as a bell right now at 2 P.M). I'm not sure how Salamander can overcome such a flaw. This is simply unacceptable for a property that seeks to establish itself as a premier destination.
The fitness, spa facilities are top notch and the common areas within the hotel were thoughtfully designed and comfortably furnished. The family pool area is adequate but does not have the set up service we've enjoyed at other fine resorts. There is a quiet pool but it is only available to spa clientele.
The concierge desk was very responsive when I called in advance of our stay to arrange for flowers to be in our room upon arrival and my wife loved them. Finally, while the service from reception and the bell desk was congenial is took more than one phone try to actually get through in order to have our luggage delivered.
All in all, despite many upsides, I'm not sure I would return due to the thinness of the room walls and potential for an uncomfortable night.
