Responsible water use
Our goal is to reduce unnecessary consumption, identify losses early and operate our equipment as efficiently as possible.
Our policy is simple: reduce the hotel’s environmental footprint, use resources more responsibly and support our local area, while always maintaining the level of comfort and service our guests expect.

We believe a hotel can offer high-standard hospitality while operating with greater respect for the environment and the local community.
At Mon Signor, we work every day to avoid unnecessary water and electricity consumption. Our approach is based on careful operation, maintenance and practices that reduce waste without affecting guest comfort.
At the same time, wherever possible, we prioritise local products, local producers and partnerships that keep more of the value created by hospitality within Santorini and the local community.
Our garden is also part of our approach to sustainability. Today, more than 250 plants grow throughout the hotel, and we continue to expand and enrich the green spaces of Mon Signor.
For us, sustainability does not mean lower quality. It means more thoughtful choices, better resource management and responsible operations without lowering our standards in cleanliness, food safety, service or the overall stay experience.
We do not treat sustainability as a separate service. We consider it part of how the hotel operates.
