Nicaragua

Hey I will most likely be going on a surfing trip for my 18th birthday to Nicaragua this April. I would be arriving in Managua, where should I stay for a cheap price, I don't mind living in simple quarters but I will be with my parents so I don't want to stay in a shack either lol. Where should I stay to get good surf, be near historic cities, and close to other cool activities? How cheap and easy is it to rent boards, and a jeep? Any tips? Thanks!
