A small receptive agency in the centre of Pichilemu, currently registered with SERNATUR. They publish one mobile, which is also the WhatsApp, and take bookings through it.
The number on their website and the number on their SERNATUR registration are not the same. The website's is the one they advertise and the one behind the WhatsApp link, so it is the one here — but confirm it before a page goes live.
