Might want to try Heredia's apartments. Simple houses and apartments (friendly management) located near the football pitch (central). Have just returned from a month's stay and found it most comfortable. We stayed in a house with 2 bedrooms, bathroom and living/kitchen area area. Think that beachfront apartments are also available.
I have a lovely 3-bedroom, 2 bathroom house, ceiling fans, full kitchen, living room, cable tv, queen beds centrally located, overlooking the central park. House sleeps six people. If you are interested, please e-mail me at firstname.lastname@example.org.
