Rose's place is pretty relaxed. We didn't see a lot of Rose or her husband, but when we finally did get a chance to hang out with them, we found them pretty hip and friendly.
The neighbourhood is pretty interesting. Gorgeous trees, pretty houses, and some good shops/restaurants etc.. nearby on Broadway and on MLK. We definitely saw some homeless people around the neighbourhood, but that might just be a Portland thing. Everyone we met around there was friendly, but it's always good to keep your wits about you.
Rose's place is a good bet, especially for its proximity to downtown and for the interesting neighborhood. (Also 420 friendly in the backyard if you want to check out the legal scene).
