Eileen’s is now Casa de Colores with new ownership. You can contact the new owners to inquire as to availability:
Vivian Lougheed in “Mexico’s Pacific Coast” (2005) says “Rooms are lovely, decorated with artistic tiles, dotted with potted plants and is spotless. This is a unique guesthouse with exceptionally low rates.” Linens and bath towels are supplied; please bring your own beach towels. Laundry service is available nearby.
