Where should I store my mercurial repo on linux?

I'd like to set up a mercurial repo on a linux machine. Originally, I was going to set it up in my home directory but a lot of different users are going to be accessing it so it doesn't seem like the best place. Can anybody recommend a better location? Or should I just go with the home dir and set the permissions accordingly?
