Good location to make early flights less painful. Ridiculous they charge so much for overnight parking. If I had known that before booking I would have picked a different hotel in the same area.

I enjoyed the stay, and the event I attended there was excellent. However, I think it is unconscionable to charge $65 to valet park when the garage is located down the street from the hotel for a cost of $6.00, but due to weather or if you are leaving in the early morning hours when it is dark and traveling alone (as was I) it is dangerous to have to enter the parking lot alone. I also thought the additional $50 early check in (I arrived at 12/check is at 2:00) was a bit unreasonable.

My room looked out onto 17th, but was so quiet. Loved the bed and the large gracious room! The continental breakfast was so much better than a few pastries and some coffee—lox, cream cheese, yogurt…a respectable breakfast with protein! The best part was taking the lite rail from the airport and walking across the street with my bag to the Oxford! All around, a great place to stay!
