Weekly or monthly rentals are easy to arrange, both in San Juan del Sur  proper and in the hills surrounding the city. For the low budget set, most Spanish schools  in town have packages combining lessons and a homestay, which can be arranged (whether or not you are attending class) for around $10 per day including three meals. Most places will cut you a deal if you stay more than a few nights.
For something fancier see Vacation Rentals Nicaragua (www.vacationrentalsnicaragua.com ), Vacation Rentals by Owner (www.vrbo.com ), or Home Away (www.homeaway.com ), or stop by Aurora Beachfront Realty (tel. 505/2568-2498, U.S. tel. 323/908-6730). A fully furnished two-bedroom place goes for $800-1,200 per week and a big house is double that. Nearly all homes come with swimming pools and sweeping ocean views.
