This is a full apartment in the basement of Aaron's house. It has a comfortable bedroom, a sitting area with a TV, a sofa, and a reclining chair, a dining room table, and a small but adequate kitchen area. A pretty standard Airbnb apartment, but it's a bit nicer than most. It's well lit, the walls have been decorated with care (which goes a long way to making an airbnb feel less like a hotel), and everything was in good shape and clean.
If you're relying on Portland's public transit to get around, then you'll have to walk a bit; it's about ten minutes walk to a major bus line. But if you're going to be driving or biking (or if you don't mind the walk), then you're set.
You do have to walk down a six-step staircase when you enter the apartment, which was no problem for me, but if you have trouble with staircases this may not be a great choice.
