I really enjoyed my stay at Patrick's place. It's located in a nice and quiet neighborhood within walking distance of the places you might want to go to as well as easy access to public transport. The place itself is lovely and has everything you need, including filtered water from the tap.
Patrick is a great host and very flexible. He is fun to hang out with if that's what you want. And if not he will give you all the privacy you need. I can't recommend this place enough if you're in the Portland area.
