Mainport’s 215 rooms have been split into five categories: City XL, Corner, Waterfront Sauna, Waterfront Spa and the Spa Suite. Each room has an in-suite spa equipped with walk-in showers, anti-fog mirrors and a whirlpool. The Waterfront Spa category and the Spa Suite even have a private Jacuzzi, Finnish sauna and a mirror integrated TV. If that isn't enough, the eighth-floor spa has a Finnish panorama sauna, a Turkish steam room, hamam, two treatment rooms and an extensive relaxation room.
The interiors of the hotel, designed by Feran Thomassen, have touches like fireplaces and panoramic windows with views of the city. In keeping with Mainport’s international influences, the hotel restaurant Down Under and bar on the Rocks are a homage to Australia, in particular Sydney. Located at water level, the restaurant headed up by chef Sander Jongenotter focuses on exceptional Australian-Asian cuisine.
Mainport is located in the area of Leuvehaven next to the historic Maritime Museum and the asymmetric Erasmus Bridge.
