One of the best Airbnb experiences I've had! Erin and Aaron's basement has essentially been turned into a one bedroom apartment that is clean, comfortable and easily accessible. I stayed here with my girlfriend and her mother for 4 nights and we could not have been more comfortable. My girlfriend and I stayed in the bedroom while her mother slept on the pull out bed. It was the perfect set up and very comfortable!
We had a car as well and parking was never an issue, plenty of street parking!
If you're looking for a private stay (or socially awkward) then don't worry, you enter through a private door. If you're indifferent or looking for a little social interaction, no problem, they have a beautiful patio that is available to drink coffee or relax on and you may run into the friendly and gracious hosts.
Only warning for potential renters is that the ceiling is a bit low but will only be a real issue if you're a pro basketball player (or the size of one). Also, be aware that they have two little ones who you may hear running around and playing upstairs in the morning but it's never at an unreasonable hour or an issue at all (and trust me when I say this because I am NOT a morning person).
Will definitely stay here again for my next visit to the Portland area!
