We enjoyed our 1-week stay at Rebecca's place. Checking in and out was trouble-free. The place was very spacious and easily accommodated our 5-adult group. There were a lot of nice touches such as Netflix, lots of towels/sheets, tea/coffee, and cookware (although table spoons, the kind for for eating soups, would be a great addition :)
The beds were comfortable and the shower functioned very well.
The place is located in a quiet residential area. However, it is within a 15-minute walk to a MAX station which is good for exploring the city and getting from and to the airport.
Overall, I highly recommend Rebecca's place as the home base for your visit to Portland.
