We stayed in Portland only for one night, on our way to the southern coast. Melissa's place was perfect for a quick stay (and we would love to stay longer, when we have the chance). It's not located in the center of the city, so it has ample parking, yet it's very close to Alberta street, where we found cool stores, cafes, restaurants, bars and even yoga studios. The apartment itself is small but very cozy and nicely decorated. We had a great time here, and hope to return.
(we also highly recommend the Ethiopian restaurant nearby :) )
