Check-in at Erin's was very easy, she gave us great instructions on how to get in and exactly where the private entrance was located.
The place looks EXACTLY like the pictures, very clean and modern. Erin stocks the fridge with drinks, both alcoholic and non-alcoholic and gave us a nice little welcome basket of food! Erin herself is very kind and easy to reach, she was always willing to give us great suggestions on where to go and always answered any of our questions promptly. She was even kind enough to let us checkout later when we gave very short notice and only asked the night before when we checked our flight times!
The only slight downside to Erin's place would be the location, it is located a little ways outside the city centre. If you have a car it will be no problem to travel to and from her house, the area is very easy to drive in. If you are like me, with no car while there your best bet will be to use the transit system (cabs in Portland are expensive) and luckily there are several stops close by.
