What many Varsovians know as the Prudential Building, an iconic pre-WWII tower block, has been transformed into this swoon-worthy hotel. The radical makeover both respects (and reveals) the building's concrete bones, adding lustre through judicious natural materials, including copper, marble, granite and fine-grained wood. Some may find it stark, we find it incredible.
In the basement, as well as the pool and spa, you'll find the dramatic restaurant and bar Warszawska.
