Vaychee is a great host. She responded to every message I sent (before and while visiting) within minutes. She is personable and thoughtful.
The apartment has everything you could need, from shopping bags to a Theracane(!), and if there's something missing, she will be happy to find it for you. I asked if she might have an insulated-type bag I could use for the week to bring my lunch to the UW lab where I was working, and she knocked 10 minutes later with two options.
Everything in the description for the apartment is absolutely honest. The bathroom is not built for tall people (over 6' and you might feel like you'd bump your head all the time), and the house upstairs is a family home where they live day-to-day with teenage kids. I had no problem with the family 'noise' - people going up and down the stairs, for example - it was nothing more than you would hear if you lived in a city apartment. If you prefer a firm mattress, you probably will find the mattress too soft for you, as I did.
The garden is lovely, with tables to sit, and *especially* if you are in town for something related to UW, the location is excellent. I absolutely recommend this home if you're in Seattle.
