Mantera Supreme Seaside is a large-scale luxury hotel complex with club residences. Located in the "Sirius" federal territory, in close proximity to the Olympic Park. This 6-hectare coastal space combines architecture, service, and infrastructure for leisure, living, and business events. The eight-story, five-star hotel includes 400 designer rooms—from sophisticated suites to suites with private pools and spacious terraces. The top level of the complex features rooms with infinity pools and panoramic terraces overlooking the endless Black Sea.

The Mantera Supreme Seaside culinary concept includes 11 restaurants and bars with signature cuisine and expressive interiors. The spaces are designed to be equally comfortable for leisurely dinners and vibrant evening events. For relaxation and recuperation, the complex offers a modern fitness center, a multifunctional spa complex, a private beach, and a kids' club with educational programs.

Mantera Supreme Seaside is also designed to host events of any scale. The high-tech Sirius Conference Center accommodates up to 1,320 guests and includes two large, transformable halls and several private meeting rooms. It's ideal for international forums, presentations, and business meetings.

A separate area of the complex is occupied by Mantera Club Residences—apartments available for purchase and permanent residence. This is the perfect choice for those who prefer seaside living with access to all the hotel's amenities.
