Sandra's place was one of the best AirBnB experiences I've had -- excellent communication, spotlessly clean apartment, and an accurate listing. Sandra was easy to reach, and even allowed us to check in early / check out late. It's a basement unit, so even though there isn't AC, it does stay cooler than outside. Plus she provides a couple of tower fans, and you can always open the window to let in a breeze if you get too hot. There are heaters, but we visited during summer so I can't speak to their efficacy (although I bet they're good!). No complaints from us, and I wouldn't be surprised if we try to come back the next we're in Seattle!
