At Sir Nikolai, every room and suite is designed to provide a distinctive experience. The rooms' tasteful amenities, custom-designed furnishings, and sumptuous bedding combine old and modern design elements to satisfy even the most discerning tourists. Large windows, exposed brick walls, and original architectural details lend an air of industrial chic, and the whole look is accentuated by modern artwork and chic lighting fixtures.

The magnificent atrium, the focal point of the hotel, is one of Sir Nikolai's most notable architectural features. With its glass roof and abundant vegetation, this gorgeous room provides a calm haven from the busy city outside. The hotel's ability to harmoniously combine indoor and outdoor components to create a space that feels both spacious and intimate is best demonstrated by the atrium. This blending of styles is further demonstrated by the hotel's restaurant, IZAKAYA Asian Kitchen & Bar, which provides a distinctive dining experience that combines Asian flavors with a European twist. The restaurant's open kitchen, elegant bar, and creative décor all reflect the hotel's general theme of modern elegance mixed with a diversity of cultural influences.
