If you're looking for a peaceful, convenient neighborhood stay with a knowledgeable host, the Plum Room - Hummingbird Farm may be the spot for you. It's conveniently located a few short blocks from public transportation (a 10-minute walk maybe - and I had a guitar, a backpack and a carryon suitcase in tow...).
The Plum Room is also walking to a wide variety of restaurants. You'd be able to sample Thai, Cuban and Caribbean cuisine as well as get a great cup of coffee. You could also pick up groceries if you wanted to.
Not only has Dr. Inge transformed this nearly 100 year-old home into a suburban oasis, she knows her community and is willing to share her recommendations and experience. She's warm, gracious and open to sharing a meal or two as her time permits.
If you're looking to uplevel your stay in the Portland area, I'd recommend you choose the Plum Room at the Hummingbird Farm. :)
