Loved staying at Jenni's house! Exactly as described, and it was nice to have access to a whole house that someone actually lives in as opposed to staying somewhere with a sterile hotel feel.
Pye is indeed the biggest dog I've ever met (he is literally bigger than me) and he will bark a lot when you first come in, but after he was introduced, he was very sweet. He seems to just nap around the house most of the time, but he does bark at passerby sometimes at night, so if you are a light sleeper you may want to consider another place.
Location is great — it's near a bunch of bus lines that go to downtown and the convention center, and there's a grocery store about a few minutes' walk away. I'd stay here again if I return to Portland.
