Taxis in north of the island

Hi all, last year we stayed in a villa in San Rafael and although waiting times for taxis was long they did eventually turn up. We are thinking of going further north next year, possibly around the Sant Miguel region. Does anyone know if there are taxis/taxi ranks that operate from locations other than San Antoni and Ibiza Town? Anyone any experiences of getting taxis from further north? Bit worried we might be stuck for getting taxis down to San An and Ibiza Town.

Many thanks.
