Pamela is a fantastic host who will welcome you to a beautiful and scenic home with lots of nostalgic 60s to 80s style. The apartment itself is a private sub part of the house with a half-bathroom that is completely yours to use.
The area in which the house resides is quite quiet and central enough for you to reach the next public transport (several bus lines and a train line departing in walkable distance) easily.
I would definitely recommend staying at Pamela's place, but make sure to book a good bunch in advance - this rental is very popular among Portland visitors!
