medyani is about to use it to adventure around for about 6 months. While I don't have any personal experience with it, in a month or so, she'll be able to share plenty of hers!
I have some friends who've used it and thought it was great, but also had a friend with a roommate who used it exclusively to host hot women and try to hook up with them. I suppose the upisde is you're more likely to have options and the downside is that you're more likely to have potentially creepy guys trying to sleep with you.
