I loved this place! It's very comfortable, has all the conveniences and amenities you might want, and the original art on the walls is all extremely cool. It's also very quiet, even in this bustling neighborhood--you will get a good night's sleep.
As for the location: There is no place better to be in Portland, in my opinion. It's an easy walk to the Pearl District and downtown, the streetcar (light rail) stop is only a couple of blocks away, and you're in a real neighborhood but also just half a block off NW 23rd, which is full of shops and restaurants of all kinds.
Fred was a great host--he was in touch promptly, and quick to check in with me to make sure everything was going well.
I'll definitely stay here again if I get the chance, and I will be recommending it to my friends who come through Portland.
