Zero Stars Hotels
Detailed presentation
Zero Stars Hotels is a Greek hotel booking platform where travelers save more, hotels earn more, and sustainability is real. Guests design their ideal stay with Zero Rooms—the world’s first fully custom-made room experience—and unlock the best rates with Sustainable Rooms by skipping energy-heavy extras. Hotels enjoy ultra-low commissions from 5%, total control of their pricing, and no competition from other types of accommodation. A smarter, fairer, greener way to book.
The problem
We tackle key hospitality challenges. For guests: limited ability to personalize their stay, unclear environmental impact, and a growing need for affordable yet meaningful travel experiences. For hotels: rising costs, low occupancy in off-peak months, high OTA commissions that reduce margins, growing pressure to meet climate targets, and competition from short-term rentals. Our solution: a new hospitality model with Zero Rooms (customizable stays), Sustainable Rooms (real CO₂ reduction), patented impact tracking, and Eco Elite—a loyalty program rewarding greener choices. With us, hotels benefit from increased profits by up to 40% and cut emissions by 20%.
Our proposal
Our hotel booking platform introduces two groundbreaking accommodation models: -Zero Room — the world’s first 100% customizable hotel room, where guests choose exactly what they want and pay only for what they use. No wasted services, no unnecessary costs, no hidden fees. Travelers gain true flexibility and lower prices, while hotels reduce operating expenses and maximize their margins. Sustainable Room — a new model of eco-conscious hospitality. Guests are transparently informed of their environmental impact through our patented CO₂ Calculator and are rewarded for sustainable choices with better rates. Hotels achieve measurable reductions in emissions — up to 20% — without any capital expenditure.
