We got to the Airbnb and were greeted by Debra. She showed us how to enter the Airbnb by walking into the side entrance to the backyard. David and Debra had offered us some free things to drink and eat and some clean towels to use for our stay in Portland. The Airbnb is super cozy and filled with books all over the place! There were some nostalgic video tapes and DVDs of my childhood movies. Although we weren't inside the Airbnb most of the times, we were able to sleep and enjoy our stay.
A few things to note would be that the outlets don't really work in both rooms. Since the Airbnb is actually an in-law unit underneath the house, you'll hear footsteps from upstairs.
Overall, it has been a pleasant experience and I would definitely book with David and Debra again.
