The apartment had everything I needed for my stay in Portland, and I appreciated having a full kitchen available. The location was within walking distance to the Convention Center (assuming you don't mind a 15-20 minute walk) and I found many good restaurants within a 20 minute walk or bus ride. I didn't interact with the hosts very much, but what interaction we did have was clear and helpful.
Two small notes:
1. The door lock may need to be oiled or looked at by a locksmith - I had some issues with my key sticking in the lock when I would lock or unlock the door.
2. Because I am paranoid (as some of us women traveling alone have learned to be), I would have preferred for there to be a curtain or blinds over the window on the door leading into the unit since that is the only locking door (other than the bathroom) in the unit and the lock on that door is a turning knob dead bolt right next to the door window. Of course a curtain or blinds wouldn't actually help in the event of a break in, but it would have given me more peace of mind as a preventative measure. I suspect many other folks might not even notice this, and to be clear, I never got the impression that the neighborhood was unsafe.
