Hello!
Campsite Siurana is I think the best place to meet climbing partners. It's very close to many of the sectors and generally a lovely place to hang out.
From what I remember it's 7 euros for camping, and 12 euros for a bed in a communal room. Clean showers and toilets and also delicious food at the bar. Oh, and if you're into coffee, it's very good as well.
