Yeah agree. It was the cause of the only occasion I moved out of a place due to house mates. Was nothing personal, but yet another person sharing 1 bathroom, 1 kitchen, etc in an already fullish house without paying anything was not good.Oh yes. This is a good one.
Be aware of the flatmate's freeloading GF/BF.
I did also live in one place where there was a couple but I came into it knowing that and was no problem really.
