First, the space is amazing. I got a welcoming sense from the moment I opened the door to the walkway alongside the main house - the landscaping is pleasant and inviting and opened right into the "tiny house" in the back. The space is cozy and very quiet for a single or couple visiting Portland. Everything I needed was there, whether the kitchen or towels, etc. The bed was incredibly comfortable, and everything was just so clean. The shower was immaculately clean. The decoration throughout the space was groovy - just enough to give the space a personality without cluttering it.
Second, the location is great! The home is straddled between two streets, Hawthorne and Belmont, full of eclectic houses from the turn of the century that are painted vividly with cheery and bright landscaping. Both streets have a lot of restaurants, a few bars, and some amazing shops and activities. Had the chance to check out the Belmont Street Fair while I was there, and that was a fun taste of Portland I wouldn't have gotten staying at the hotel for our conference. It's a $8-12 uber trip into downtown, and I never had to wait more than 10 minutes for an uber.
The neighborhood is very "runnable" for runners - Portland overall seems to have more than the average amount of runners, and a ton of bicyclists - it's a little dark if you run before or after sunrise, so bring a headlamp or flashlight. :-)
I really enjoyed my stay in Portland and at the tiny house, and will plan on coming back when my wife and return to Portland for a vacation!
