Not knowing portland i unsuccessfully looked for an airbnb in the downtown area. It's a good thing i didn't find anything there since in general that area of town is as exciting as the financial district in SF, which _ if you're not familiar with san francisco _ is an area filled with depressing 70's hi rises with a small scattering of lunch places that cater to the office workers in the area.
The area where Susan's cottage is located though _ known as the LADD addition _ seems to be very vibrant and filled with fun little places some of which have because famous (like stump town coffee) while others are unique to the area (i recommend left side roasters which is only a 5m walk from the cottage.)
Unlike many other airbnb-s, susan's place is well stocked. Normally i have to go out and buy a bag full of basic kitchen items like olive oil, salt, pepper, dish washing liquid, tea + coffee (susan offers a hi quality dark roast with bean grinder and chemex/french press.)
One bnb i visited didn't have knives to prep food. Susan has a full set so you can cook like you're at home (i remember seeing a blender as well.)
The cottage is in a residential area so it's nice an quiet at night. The cottage is right next to a vegetable garden and (susan can correct me if i'm wrong) i think you can actually pick vegetables from there to use for your meals. There's an awesome grocery nearby (new season market) where they sell locally made goat cheese and lots of other goodies. Definitely recommend this place to anyone visiting portland.
