I was saddened to read such a negative review, but I'll take some time to address your issues here. If you're thinking about staying here please look through the other reviews and don't put too much into Marc's inane ramblings.
A) You wanted new sheets so badly that you never asked for them. It's not a hotel, it's an Air BB, so if you'd like something you should ask.
B) My wife's parents came up to see her for her birthday so those were the rowdy guests you heard. I tried to apologize for the noise (which was really nothing crazy), but we lead busy lives that can't always revolve perfectly around your schedule. Quite frankly for someone that got up multiple times per night and left a toilet full of smelly urine waiting for me each morning I thought that maybe you'd be more accommodating to the small inconveniences of co-habitation. Guess not.
C) If you felt you paid too much that's your opinion and you're welcome to it. I would recommend that if you come back to Portland you check the rates on local hotels and other Air BBs and you'll see that we're actually on the low end. My suspicion is you did that this time and that you're just cheap.
Before I read their review I would have recommended them but after this I'd say to turn these folks out on the street like miserable curmudgeons that they are.
