Service, service, service. When the people at a hotel are wonderfully pleasant and helpful it is hard to find anything to critique! To be clear, this Westin is not within (safe) walking distance of anything. You either need a car, or a car service otherwise you will feel a little isolated. Nevertheless, the isolation is worth the quiet and calming atmosphere of the hotel. I would think that this is the perfect place for a business traveler who will be working in Reston/Herndon for a few days. It's clean, elegant and very easy to luxuriate in. It is also all very well kept. That said, the one little negative we have is that there was mold or discoloration in the otherwise gorgeous shower. Clearly, it was not enough to cause us to get down on her hands and knees to examine more closely, and I have no doubt it was rectified after our departure (we took the option of not having maid service every night). We would definitely stay here again.
