I spent 4 nights and everything was great. This was my first airbnb and I really appreciated that Jacob's post answered a lot of my questions up-front (e.g. 'is it ok to use the kitchen or laundry' [yes!] or, 'where do I put recycling', etc.).
Jacob was a great host. He's chill, friendly and knows Portland. He'll give you tips on good local spots. He'll interact as much or as little as you want. It was nice to chat with him, and I appreciated that, when I wasn't feeling social, he gave me as much space and privacy as I wanted.
It was a short walk to the MAX & bus stations so I didn't have to drive the entire time I was there. It's in a nice, quiet neighborhood and I liked that he had nice chairs for relaxing on the porch and patio. The bed was comfortable and there were plenty of drawers, and a good sized closet for stuff.
This was the perfect place for what I needed. Defiantly a 5-star recommendation from me.
