I can recommend Joann's place wholeheartedly. While not entirely private as Joann occupies the other half of the house, she goes above and beyond to make it feel completely private while you are staying there. The space was also exceptionally clean and well accompanied. The adjustable bed was also easily my best nights sleep in an Airbnb. We love St Johns in general, but I'd recommend being familiar with the area before committing to staying there when visiting Portland. Luckily we are very familiar and have friends in the neighborhood. Highly recommend!!
