This is a GREAT place - so much room, extremely comfortable, NOT A BASEMENT (nothing wrong with a basement, lots of airbnbs are in basements, but i prefer a wooden floor with spring to a concrete slab and a view looking down at the streets, yards etc rather than up at the bottom of trees, dogs at eye level and people's shoes.)
The third floor extra bedroom is a true bonus and made this very affordable place even more so.
I had absolutely no problems with this rental (other than trying to find it on the dark dark Portland streets (the use of more widely spaced narrow focus lower level street lamps rather than the closer together, extra bright LED lights like Seattle uses) was one reason for the poor visibility that caused me to have a bit of trouble fnding the house ( as well as the fact that it was raining and dark and rainy) (Plus, oh yeah, I had memorized the off by a digit street number and promptly forgotten it - that may have assisted the confusion a bit.)
This house only had 3 reviews starting last month or this month. I suspect it must be a new on the airbnb listings because it was a spectacular place. Definitely consider it the next time we're in Portland (and in fact it may be the reason for furture trips.)
