Opal & Palm is the first hospitality certification company built exclusively for short-term rentals, vacations properties, and private residences. We assess properties against The Opal Standard, a five-pillar framework built on 18 years of ultra-high-net-worth hospitality experience. Every certified property receives a full written assessment, an Opal Score out of 100, and the Opal Certified mark. A signal guests can trust before they book.
