As someone who spent 5 straight days at the Emerald City Comic Con, i would highly recommend that. It's an unequaled spectacle in the heart of downtown Seattle that draws positive people in costumes from all around the world. I didn't get to see much otherwise but the Seattle dinner culture has great options, like Din Tai Fung Pacific Place. Ba Bar right around the corner was aaaaamazing and open until 2am.
The apartment was perfect for my needs. It was clean, quiet, very secure, stocked with great resources (I had to steal some band aids) and didn't have any of the weirdities some other AirBnBs I have used boast of (smells, stains, guest leftovers, unexpected wildlife) and the quality of the towels was top notch: clean and fresh, new enough not to feel broken in.
I can't currently relate on any improvements. If I had had more time to engage it properly I may have noticed something but I didn't. Only thing I can think of: no idea how to turn off the lamps in the main room.
Thanks for the great stay!
