Our stay in Karma's house was lovely! The property is in a very walk-able neighborhood. We walked to dinner one night and walked back from Salt & Straw, and roamed the neighborhood one morning and passed lots of adorable restaurants and shops.
The house itself is lovely. Two rooms upstairs with comfortable queen beds, a fully equipped kitchen, and Karma has left lots of extras like tea/coffee/toiletries for the use of her guests. There is wifi, cable + HBO, and a wide selection of books to keep you entertained. Though we spent most of our time exploring Portland, we also spent a fair amount of time in the house (lazy mornings, relaxing together in the living room in the evenings) because the place was so pleasant! Highly recommend.
