Excellent, superior Airbnb with one major caveat for some guests.
It's a beautiful, brightly sunlit house with great places to work and hang out and a good kitchen. There's a perfectly sited porch that gets dappled sun throughout most of the day. This is where I did my remote computer-based job during the day and it was great.
The house has a cool history that the owners honor. I have stayed in about 25 nice Airbnbs in the last year and this one is in the top 2-3 aesthetically. There are neat old books to look through and a piano which is playable if not totally in tune.
The location is also perfect: This neighborhood is way more cool than the last time I lived in Portland. It's quiet and peaceful yet you have friendly neighbors out on their walks and a couple of great coffee shops nearby.
The hosts were friendly and provided some extra equipment that I requested (a HEPA filter) and helped with a wi-fi issue. The Internet connection itself is very good (>200mbps), but the wi-fi coverage could be improved. The back yard is useful for workouts or hanging up clothes to dry, but could use some more work to be a little more comfortable and private.
The one major downside is that the attic is used by the hosts, they're up well before dawn, and even though they're quiet, there's just no way for them to move around up there without waking you. Unless you're a very heavy sleeper or early riser, consider this carefully. (That said, they were out of town for most of my stay; maybe the early mornings aren't typical? Not sure.)
Overall, I loved my stay and would happily stay again.
