I wouldn't, for not only the obvious reasons but also because I wan't my own space. Sometimes it is difficult sharing with a close loved one, can't see it for an acquaintance or stranger.

I have even read stories here in the U.S. that had squatters nest in peoples homes while they were away (the one coming ot mind seems they were off for the military) and when they came back the cops refused to kick them out even though they were never given permission to even trespass as they were.
