I remember those when I was 16. Do they still have them?
I’m guessing they still do in Europe. Although I’m not sure if they are still catering to the middle-class white college student anymore like they did when I was there.
They are all over Europe. The ones in large cities are usually college aged party spots where you run the risk of losing your possessions and gaining an STD. They range from pretty nice to downright flop houses. There are some family friendly ones out there and some designated as elderhostels.
