Overall my stay with mike was a great experience. The check-in was very easy, thanks to the detailed instructions he provided. The room was very clean and well equipped however pretty small. Mike provides his guest with a folder containing food and sightseeing recommendations as well as general travel tips, which is really great. The bathroom was spacious and really nice as well.
You can reach downtown Portland in 30 min by public transport. The house is located directly next to a big street, so you can always hear traffic noice. Inside the house it´s surprisingly quite, the traffic didn't bother me at all. But if you have a light sleep, this might to be the case for you.
Mike is a really nice guy and a great host!
