Seattle is a most fantastic city, in that nearly everything you need to learn about the city is already on the internet.
The neighborhood is called "Lake City". You can read about it here:
Lake City, Seattle, Washington - Wikipedia, the free encyclopedia
And here:
Outer limits: The Lake City blog
As far as transportation is concerned, go here:
Trip Planning
To find out what buses go to downtown, you can use the following intersection as a destination: "3rd and Pike".
To find out what buses go to the University District (assuming that you would be going to school at the UW, if not, let me know), use the following intersection: "45th and University".
I don't find myself in that part of the world too often, so hopefully someone else can give you more of a skinny on the place.
Good luck!
