First off: We would not hesitate to stay here again and had a wonderful time in Portland! If you are unsure a few points of note:
The House: ...is renovated and furnished with a lot of love and artistic talent. It is a shared/hostel space so you *will* meet other people staying here, which for us was a big plus.
Noise: The house is located directly next to a busy street and has very thin windows/walls, so there is significant noise from passing cars throughout the day and night.
Kitchen: There is a fully usable kitchen with everything you need, but as it is a shared space it is somewhat cluttered and not super clean, so be prepared for that.
Evan: ... is a wonderful host with an amazing ability to create a community on the spot and just a pleasure to be around. He is reason enough to return.
