Not the best Seattle airbnb but not the worst I've stayed in. It definitely is a basement you are staying in, separated only by a door (which has no lock on your side - making it feel a bit uncomfortable to have no control over that). The first night we could definitely hear them upstairs - talking, closing doors, walking, their wakeup time around 530 am the next morning, etc. We were worried about rest of our stay but the remaining nights we didn't hear them at all.
These is no control of temperature in the main area (one bedroom has a heater that cannot be moved and the other has like baseboard heating), so we were frequently chilly in this area. The room temperatures were difficult to get right - it was either too hot or too cold. They also each have large windows with basic blinds or none, which means lots of sunlight in both rooms at all times and in one, porch lights shining in at night. Would have liked blackout window coverings or better curtains as we both had to buy sleep masks for darkness during sleep.
Our biggest complaint about this airbnb was the location. The neighborhood is a bit sketch and we were hoping to walk places, but there's not many businesses nearby and we didn't feel safe doing so. There are a couple good restaurants but not many other places worth noting. The location is also away from most other fun neighborhoods, requiring a decent drive if we wanted to go somewhere else. It's a bit out of the way and we most likely would not stay again due to this reason.
Otherwise, the place was clean, the hosts were friendly, there's TVs, games, and movies for entertainment with cookies welcoming us upon our arrival. The beds were comfortable, the kitchen adequate, and the bathroom was okay but a bit awkward (the shower especially is tight if you are tall). We also appreciated the two rooms with two separate beds as this was hard to find for us. Price seemed like a bit much for what it was, but we would give it a 3.5-4 star.
