Seattle is a great place especially when the weather is nice. I use to live in the city and I rented a cheap room from a family. But I know it's a little more difficult now since it's become more expensive these days.
I hope you the best and also be sure to go outside the city whenever you can because there are a lot of cool places to take footage. Over the mountains, it changes to desert so it's a cool contrast to green cooler side of the state of Washington.
