Ngone's place is a studio they have over their garage. It is very spacious and close to the Hoyt Arboretum and its surrounding Portland attractions. Downtown Portland is also within easy driving distance. (I'm not sure how long it would take with public transit). The gas heater was effective, but being a wimpy Californian, I would have appreciated extra blankets.
All in all, I would recommend a stay here, especially to those traveling with a car :)
