I've stayed off and on in PDX for business at several Airbnbs around the area and Kalyn's place was my favorite. Easy non-contact check in, very clean apartment, hand sanitizer and cleaning supplies easily accessed (made me feel very safe considering COVID). Small comfortable unit with everything you need in a great neighborhood. I walked in to snacks, parking passes, and a very clean kitchen and bathroom (not a given at other Airbnbs).
The space is easy to settle into and the neighborhood is very walking friendly with tons of restaurants and services near by.
I would recommend staying again whether for business or just personal travel.
