Just how often does that happen?
Fairly often, I've had a couple people stay 8-10 times even, a few days at a time. I had someone stay last week, that I hadn't seen for over a year and a half too. But a bunch more that have stayed maybe a couple times.
I don't like the idea of long term renters
After the initial first few weeks they show their true colours. People get to the settled in point. Some people are naturally bad to begin with, but even people that might be great for 2-3 weeks might just be putting on a show for you. haha. I cap it at 4 weeks, generally don't see longer than 1 to 2 weeks though.
I would think hosts get to rate their guests, too, right?
Yup, I had a guest recently that turned up drunk and puked on my carpet, I gave him a bad review and he was literally begging me for forgiveness in the chat after my review came out. He wanted me to change the review, but once both sides are posted that is it, they can't be edited. No chance I would edit even if I could.
