A 4:00 PM check-in time while pushing a $20 "early" check in time is an egregious money grab, especially when there are fewer than 10 cars in the entire parking lot when we arrived. I will no longer book your hotels if the check in time is not until 4 pm. The lobby bar and restaurant business hours were very haphazard.

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!
