Jodi's place was my first time staying in the Sullivan's Gulch neighborhood, and it felt very safe and pleasant. I found the space to be quiet, unassuming, and welcoming. There is a nice deck to enjoy cool evening breezes, a small but well-supplied kitchen (stove, coffee maker, large fridge and freezer, nice little dining table), and a comfortable main room. Checking in and getting connected to WIFI was easy.
I was attending a conference downtown (near Powell's), and I found I was able to walk straight to the venue in about 40 minutes, with a great view from the iconic Steel Bridge along the way. It was also less than a 10 minute walk to the MAX station servicing the airport. So, a good choice if you're looking to avoid a car rental (which I recommend, Portland is one of the few cities I've been where you can get away without a car so easily!)
Would definitely recommend.
