We had a great stay in Portland at Fred's place. The location is so, so convenient - we were able to walk to nearly every place we wanted to go during our stay, and when we took public transportation (the streetcar or the bus) the stops were very close to the apartment.
I was surprised at how quiet things were in the apartment considering the close proximity to NW 23rd Ave, which is pretty busy - but noise from the street was never an issue for us.
Fred was really prompt and attentive with communication.
One thing that I think could be a little bit more clear in the description is that the bedroom is in the front of the house facing the street - there is a considerable amount of light entering the room at night.
