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.

This was our third time staying at this particular hotel in the last 10 years so we have a history to compare it to. It will be the last time we stay here. For the room price and the options that you have to DEPEND on the hotel staff to provide for you in a timely manner, it wasn't worth it. Nice property to look at though
