I highly recommend Mike's apartment in NE Portland. The apartment really made our trip extra enjoyable. It's new, very clean, comfortable, spacious and will appointed. It's in a quiet neighborhood called Concordia, which is mostly residential but also has a bunch of restaurants just half a block away -- some of them very trendy /upscale. It was great having a full kitchen, so we didn't have to eat every meal out.
Mike is a terrific host and a really nice guy. He left a bottle of wine for us, which was very gracious. He makes himself available if you need him, but isn't intrusive at all. The beds were comfortable, the shower was excellent, and it was really nice to have the big TV with Netflix to watch movies in the evening. I would absolutely stay here again on another trip to Portland.
