Great location
This is your typical Hilton Hotel. There is nothing that really stands out about it except for its central location - within walking distance of everything downtown Seattle and close to the I-5 ramps. 
Because the parking garage is on the first 9 floors of the hotel, the hotel lobby is on the 10th floor. There no windows (ie: natural lighting) and the dim lights make the lobby feel not very welcoming. The rooms are pretty standard but come with pretty nice views of the city. The bathroom was very small and it was difficult to close the bathroom door while I was standing inside. I also thought it was strange that the toilet didn't have a seat lid.
Will I stay here again? Probably since I am Hilton Honours member but this is definitely not my favourite HIlton Hotel.
