Do you want to check out apartments or residential areas at all?

If you're going to work in Hillsboro & like to ride, I'd check out the areas around Orenco Station (where you'll be staying, conveniently...), and near the Streets of Tanasbourne.

Orenco Station is the area off of Cornell, west of Cornelius Pass Rd. There's a light rail station there, and a hub of development off of it.

Streets of Tanasbourne is an outdoor mall, which is between Cornell & Evergreen, just west of 185th Ave.

Both areas are close to lots of shopping & restaurants (lots of chains, though), and both would be good bases for riding on the rural road of Washington County.

It's more suburban out there, than Portland proper, and doesn't have as much cool/unique/funky stuff going on. But lots of good riding, and close to a lot of high tech work places.
