The whole apartment occupies the basement of a house, but there is plenty of natural light, so you would not feel like you are in the basement.
Kristen and her husband were amazing hosts: very easy to communicate with, fast response, great recommendations...( we had the best dinner as a group based on their recommendations)- a tapas place toro bravo within walking distance from the apartment.
The apartment is sparkling clean, spacious, large bedroom with plenty storage, bathroom has a tub- if you travel with small children always a plus) and a very nice and stylishly decorated living / kitchen area.
It is 15 mins walking at a leisurely pace from the convention center and you can find on your way there a Walgreens, two Starbucks, chipotle, and some other places to grab a quick bite.
Kristen was gracious to allow me to store my luggage and change even before the check in time ( but I was there and had to run to the conference), so she was very accommodating!
I will definitely return if any future conferences are in Portland!
