My group of 7 had a fantastic time staying at Kerry's place in Portland. It's within walking distance of a Voodoo Donut, which became a pre-brunch ritual. There are plenty of good restaurants in the area as well. It's quick to get to downtown by car, maybe 10-15 minutes.
We really appreciated the list of local recommendations, and found the OHSU sky tram to be a fun and quick way to see the city.
I would recommend this place to anyone with a large group, as it is clean, comfortable, and quickly becomes more economic than a hotel.
