Derek's house was very comfortable for two sets of in-laws visiting their kids. It was a nice refuge from the one day of rain that we had; we didn't feel the need to escape. We did not get to meet Derek, as he was on his own vacation, but Todd his neighbor was very responsive to any questions that we had.
We enjoyed exploring the Alberta neighborhood with the interesting shops and restaurants.
I would certainly like to book Derek's place again, the next time we visit our son and daughter in law, and recommend his place as a great base to explore north east PDX.
