You know, where you spend half an hour speaking to someone in your language and half an hour speaking in theirs, one on one? People usually organise them through gumtree or things like that.

Basically has anyone done this? I'm looking to work on my Spanish once I get back from Canada, and there seem to be plenty of people who want english speakers for Spanish. However, is it just going to be guys attempting to sleaze on women? Or will I be killed and eaten?

Advice/experiences/puns below please.
