Nice stay for the price. Small and pretty basic, but it cost less than most of the other AirBNBs we've stayed at in the area and the space was what we expected from the description and pictures.
The unit had a private keyless entrance that is separate from the owner's main entrance. However, there is a door that leads from the owner's part of the house inside the rental unit and there isn't a privacy door that can be locked (at night, for instance). This isn't uncommon for a basement apartment, and probably not any less secure than a house when the owner has a key, but it would feel a little weird to me if I was staying somewhere as a woman alone.
Good choice for a couple for a weekend. Very convenient to the University of Portland and St. Johns. Bed was comfortable and the space was quiet. We enjoyed our stay.
