I was staying there for a little over a month. I mostly enjoyed my stay, hosts were very responsive and helpful and provided everything that I needed during this time. Due to coronavirus pandemic and the probability of me having trouble going home, they even offered me to stay after my reservation is over, with no charge. I really recommend this place if you want to see as much of Seattle as you can - this place is located in the city centre, and I was able to walk anywhere in the city from there. There are plenty of grocery stores in the neighbourhood, as well as bars, restaurants etc. The bed was just amazing - probably the best sleep I've ever had in my life. Kitchen is rather small with basic equipment, but you would probably be fine if you don't plan to cook a lot.
However if you are looking for some quiet place where you can rest peacefully, I would suggest to look for something else. Keep in mind that this unit is located in historical building on one of the most busiest streets in Seattle so you can imagine it can get pretty loud. There is fire department almost in front of the windows and you can hear the sirens through days and nights. I also had some issues with neighbours that were way to loud, but hosts were trying to fix that. It looked like they moved away in the time when I was leaving, so maybe future tenants won't have the same problems as I did.
