Wellness is a recurring theme at Mainport, a harbor-hugging city hotel
with an envy-inducing location in central Rotterdam. Many of this sleek
black building's 215 rooms have facilities usually reserved for hotel
spas, like oversized hot tubs with views across the city, or private
Finnish saunas.
Wide glass windows wrap around the waterfront building, allowing guests
to see and feel the vibrancy of the inner harbor, with its famous
cable-stayed bridge and easy water-taxi connections.
