The 303-room Ritz-Carlton, located near Postdamer Platz, is one of the most luxurious hotels in Berlin. The rooms are gorgeous in a classically elegant way, featuring mahogany furniture, rich curtains, plush bedding, and massive marble bathrooms with separate soaking tubs and showers. Modern amenities include touch-screen controls and large flat-screen TVs. Wi-Fi is available, but it comes with a pesky additional fee. The hotel has plenty of amenities, including a large spa, indoor pool, sauna, and fitness center. There are also several dining and drinking options on-site, along with 24-hour room service.
