Yoga Retreat Recs Spain/Portugal for 20somethings

I am overwhelmed with options and would love to know peoples actual expereinces at yoga retreats. I have really gotten into yoga and since I'm going to Spain anyways, I would love to do a retreat (amazing if it also uncludes other activities hiking, etc.) that is really geared towards young women. I see a lot that are like 40 plus and respectfully, want to yap with girls my age. Open to any recs in portugal and Spain, particuarly in May :)
