We cannot recommend Patricia's place enough. The neighborhood is charming, with the Kennedy School McNenamin's just minutes away and easy access to many of the places a traveler would want/need to go, such as downtown, the Alberta and Hawthorne districts, as well as the airport. There is a park just blocks away if you wanted someplace to jog or hang out and watch people walking their pups. Walgreens and New Seasons (kind of like Portland's Whole Foods) is nearby, also.
Patricia herself is quick to respond, and the space she provides is a welcome relief after spending all day sightseeing. The separate entrance makes things easier for those of us who get back fairly late from being out - no worries about disturbing anyone as long as you are reasonably quiet.
Patricia also anticipates needs: she knew we are from Hawaii, so she had turned the fireplace on in advance of our arrival in case Portland's crisp fall weather was too chilly for us. Towels are fluffy and thirsty; the beds are very comfortable; she provides a map of PDX to help you get your bearings and a whole bunch of menus from local eateries. There are snacks, a water dispenser, toiletries, laundry detergent provided.
In short, we loved staying there - it really felt like a home away from home. Portland is our favorite city to visit on the mainland and nothing would make us happier than to stay at Patricia's for our future PDX jaunts.
