I agree, flatshares are fabulous, but they also entail living with someone else. In this case, it would involve giving a lot of trust to an individual I have never met, and then living with them for an extended period of time. The trust issue alone is a deal breaker for flatshares, and I didn't even enjoy living with my best friend, and living with a complete stranger is never fun (college dorms). In general I prefer to have my own space, even if that space happens to be a 30 cubic foot box. I guess it comes down to personal preferences.
