I needed to move out of my previous apartment because I decided to get a cat and there were no cats allowed. I started asking friends if they knew of any vacant rooms. I had no luck until I went on Roomster. What made it so great is that I actually was able to put an ad up and specify everything that I needed, e.g. someone who likes cats! I was so happy when this guy replied; he was looking for one more person and the owner allowed pets! They were all really excited about having a pet so it couldn’t have gone any better!
