I had a great time staying at Pamela & Scott house.

The direct access to the basement gives privacy and let me come and go at any time without worry to disturb the house.
The shower, toilets, and room furniture are clean and in good conditions.

The place feels like a mini-apartment at ground level.
Being a basement the roof is slightly lower than usual, this was not an issue for me (I am 1.75m/5.75feet), but might be for very tall people (above 1.95m/6.4feet).
Wifi was speedy and easy to setup, the desk in the room let me work in the evenings.

The house is in a pretty residential area, just 12 minutes walking from the Oregon convention center and its tram station (I timed it). There residential area is very calm, I slept like a rock.

The hosts are very nice and interesting.
Overall a very good experience, that matched exactly what I was looking for.
