My sister and I visited Portland and wanted a home base so we could have our own space to go home to. We didn't want to depend or impose upon any of our friends that we were visiting. Martin and Grace's place was perfect for this purpose.
It was extremely easy to check in and out. We didn't actually have to physically meet anyone to get in the space, so there wasn't the stress of arriving at a particular time and getting in touch with someone. We just needed a door code and to let our hosts know approximately when we would arrive. I actually worried that we didn't communicate enough, but I got the send that our hosts were OK with that.
Everything was clean and we had everything we needed. The location was convenient walking distance to a nice shopping and dining district, and it was easy parking when we had a rental car.
I would highly recommend this AirBnB to anyone looking for a clean and safe stay, with lots of freedome for coming and going.
