I would ride from downtown on barbur and get on the 44 around or right after you pass the stop light at hamilton street. The 44 will take you into Multnomah Village.
Get off at 33rd or 35th, get onto Multnomah Blvd (down the hill) and turn right at 45th. You've got a fun hill to go down a bit of one to climb, not too bad though.
That's how I've gotten over there
