Lolo Pass is a very cozy and welcoming place to stay while in Portland! Great location (bus drops you off at the front door), spacious and clean kitchen, cool art gallery, coffee bar, and great workspaces (with lots of plants).
The dorm bathrooms are shared but very clean and give you a definite sense of privacy. The staff is very accomodating and friendly and they're even sending me something that I left there.

Plus, the first night I arrived they had a salsa party on the rooftop. Excellent!
