We had a great stay at Charles's place. We used it as a home base while looking for a place to live when we first moved to Portland, and it was nicely set up for such a stay (i.e. longer-term, with a bit more time being spent at home than the average tourist). It was spacious and spotless, with fast wifi. The apartment stayed nice and cool in the summer heat due to it being a basement (but not an overly dark one). Also the location is pretty unbeatable. Charles was friendly, welcoming and helpful when we had questions.
