I have stayed at many Westin hotels and I have always considered them excellent in every regard. Super value for your travel dollars! Gotta say, I was disappointed in the Westin Alexandria -- it was not up to Westin standards. If you order room service, it comes in to-go boxes, in a bag, like Food-to-Go. Plastic wear. And the menu was not at all what it should be. I ordered a Heineken that never showed up. For breakfast my mushroom & onion omelette was peppers and onions. Now I like peppers, and so it was not a problem, but .... write the damn order down so people can read it. Seriously. The in-room dining set the tone. Then, throughout the night, the toilet kept bubbling. Not sure what was bubbling, but it was bubbling up. That's reassuring and helpful for a restful sleep. I had no issues with any of the people I met. Front desk was super, parking was fast and easy, food-delivery were extremely nice. So when corporate reads this, don't go yelling at any of them. They were wonderful. But fix the other stuff. You are better than this.
