Opened on the Leuvehaven waterfront in 2013, the conveniently located Hotel Mainport Rotterdam is an upscale property with stellar wellness facilities. Designer interiors are swish, modern, and moody, and views of the water are lovely from multiple spots. The 215 spacious guest rooms are swish, equipped with Illy espresso machines, whirlpool tubs, and mirror-integrated bathroom TVs, plus some have private saunas. A pampering spa, indoor pool, saunas, steam room, and small gym are all on offer, and access is free for guests. Other features consist of an all-day international restaurant, a cocktail bar, and event facilities. For something a bit cheaper (albeit less stylish), consider the next-door [Inntel Hotels Rotterdam Centre](Inntel Hotels Rotterdam Centre), which shares wellness facilities with this property..
