The Graduate is a cool, stylish choice. It is mostly aimed at a younger crowd (we are in our 40's and were there with our daughter), but we all found it comfortable. The rooftop bar, the Mountaineering Club, is a great place for panoramic views of Seattle. The U District is as central a location as you will find, but be aware that there will be noise on the street at night if you keep your windows open. The Poindexter Cafe downstairs was a great place to grab bagels and coffee in the morning, and street parking for the night was easy to find in the neighborhood.

Fun and hip. Extra fees were a bit surprising, but staff was super helpful and location was perfect.
