A hotel with real pedigree, the 5-star Warsaw Marriott has everything from Warsaw’s classiest doorman outside to award winning restaurants inside. The accommodation has been home to a long line of visiting nabobs, including Presidents Obama and Trump. All 523 rooms and the beds are thoroughly modern and so comfortable you may not wish to leave them. Little details include lemon shampoo in the bathrooms, mini-bars complete with healthy snacks and views that stretch right across the city. The conference facilities here are likewise impressive - 18 event rooms covering 17,082 sq ft, able to accommodate 700 people, and smaller breakout rooms for more private meetings.
