Playa Roca is a nice budget hotel on the beach in Las Penitas that offers large private rooms as well as double bed or bunk bed rooms. There are also dorm rooms available at budget prices.
Its a great place to sit and enjoy a tasty beverage, while watching the waves roll in. There is a large rock out front, a great place to watch the sunset, and some decent boogie boarding as well.
Owners David & Cookie are very friendly, and will help you with whatever you may need.
