Petit Cul de Sac
Villa Cairn
3 units on the same booking site (personal-villas-st-barts.guestybookings.com) and at the same location. Each one opens its own page with every way to book it, including the host's own site.
CielStay makes the match, then steps aside: it takes no payment and no commission. Booking happens on the host's site or the platform you choose.
