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!
