The hotel and staff were good. I stay in Arlington regularly and had never used the Westin until this trip. The parking fee of $50 per day in the underground garage was steep, and as a guest, you have to pay just the same. No discount, no comp. Be prepared as this isn't stated when booking. Had dinner at the Nutrio restaurant downstairs in the lobby. Food was good and prices were as expected, however the sole waitress was also doing double duty delivering room service meals, so wait times were a bit longer for our drinks and food, despite it being quiet, with only one other couple in the entire restaurant. Its also unclear when you go to the restaurant where to find the staff. The rooms were comfortable, and clean and well maintained.
