Highly recommend Maura and Vincent's place. Location can't be beat and they did a very meticulous job renovating and converting their garage into a very comfortable guest home. The place is stylish but comfortable and a perfect homebase if you're heading to PDX to explore of if you were like, going back to visit a place you called home for a long time.
If you want to stay close to everything but in one of the best neighborhoods in PDX, I'd recommend staying here.
