We stayed for a week while our house went on the market (also in Portland), bringing lots of stuff and our dog and all her stuff. The apartment was very comfortable, lots of closet space, and everything you could need. Super quiet - except for a little bit of upstairs moving around in a normal kind of way.
It's very close to Alberta, and if you are visiting with a dog we highly recommend the dog breakfast (!!) at TinShed (book a table for brunch), Alberta Park off leash area and the Filling Station pet store.
