Good, but not great.
We stayed at the Westin as part of a small group attending a conference at the convention center, so the hotel was a nice walking distance for us each day. If you don't mind walking, which we didn't, you're just a 10 minute walk to the metro and there were plenty of places to pick up a quick drink or bite for breakfast. There was also a CVS across the street which was nice for convenience items. The staff was very helpful, especially the evening manager that was on duty, I can't remember his name, but he gave us a lot of great advice about our departure to Dulles on a very early Sunday morning when there is no metro until 7. We did enjoy the fruit-infused water while we were waiting at the lobby, but we didn't really even try any of the food or drinks provided by the lounge or restaurant because of the cost. Room service for a basic breakfast of eggs, bacon and toast (I may be forgetting something, but it wasn't anything special) for $18.95 seemed a little steep. So, we just stuck to enjoying the other local eats around town. The lobby seemed a little drab and dirty, but we mostly just cruised through to our room. We also weren't impressed as we were walking the hallway to our room as it seemed a bit uncared for and dated. We were happily surprised by our room which had the most comfortable bed and pillows and a well-working shower. There wasn't any type of operating fan in the bathroom though, so once you finished a shower, there was condensation all over everything. We left the card out asking not to replenish our towels every day, but still they were all replaced with new ones, even if they were hanging and not on the floor as requested. The apples in the hallway were a nice touch as was the one morning I found a stack of papers in the elevator lobby. There didn't seem to be a lot of noise from neighboring rooms and the room seemed to be relatively clean. One of the biggest disappointments was that for what we paid for our room, wifi was an additional charge and since we were there for 5 days, the cost wasn't worth it. Not a bad place to stay if you're around the convention center, but definitely not ideal if you want to be around the mall and other main attractions in town. In my mind, not worthy of the hefty cost.
