This is a very convenient apartment. I stayed there with my wife and baby for eight nights while we attended a conference. The place is great for a baby, since it has a lot of room to play and not many dangerous things at low height. It is close to public transport, and the Portland Conference Center. The kitchen is fully equipped, they provide plenty of towels, soap and shampoo, and the apartment has a TV, a DVD player and a Wii. The bed is comfortable.
We had a noise problem with the tenants (another AirBnb I think) above one night, but it was solved by the next night, and it wasn't the owners' fault.
The parking mentioned in the listing is street parking, but it is usually easy to find a spot in the block of the apartment.
