Most popular Craigslist-style website in Europe

I'm looking for an alternative to Craigslist while traveling through Europe. I notice Craigslist in some European cities isn't as heavly used as in North America. The alternate site should have the same sections as CS (classifieds, services offered/needed, rideshare board, for sale/rent, etc...)

Thanks in advance...

p.s.
The site should have an English translation, but it's not crucial. And sites specific to Barcelona, or Spain are prefered. Thanks.
