Carlos is a great host. We hung out the first night, and got along so well that we ended up going to Salem together to see the solar eclipse.
The property was clean, the bed was big and comfortable, and the fridge was well-stocked with snacks. The house is very close to downtown Seattle by car, and 20-30 minutes away by public transit. I had no problems getting to or from the house by bus or LINK, even late at night. As the description says, this is a bed in the corner of an open studio space, not a private room. I did not have problems with this--the only other guests were in other rooms, and rarely came into the studio space.
