If luxurious accommodations are your style, stay toward the eastern side of the city, where many of the deluxe hotels are located, including the famous Hotel Adlon Kempinski (next to the Brandenburg Gate), which was regarded in the early twentieth century as the best hotel in the world. Famous guests have included Charlie Chaplin, Marlene Dietrich, the Tsar of Russia, and currently, Hollywood celebrities.
Other 4 and 5 star establishments to consider if price is not an issue are The Westin Grand Berlin, the Hilton Hotel - Berlin, and the Maritim proArte Hotel, all located directly on Unter den Linden.
The western side of the city includes hotels in a range of prices. Many of the swankiest hotels are clustered on the upper end of Kurfürstendamm, or on its quieter side streets. Four- and five-star hotels in this area include the world-famous Savoy Am Kurfurstendamm Hotel and the Kempinski Hotel Bristol Berlin. Here is where you will also find quite a few cheaper accommodations in smaller, but modern, places such as the Hollywood Media or the Concept Hotel.
For the traveler who prefers personalized, boutique-style lodgings, Bleibtreu or Hecker's Hotel Berlin are good -- though not less expensive -- alternatives to the large hotels. Affordable lodgings that still retain an intimate ambiance are the relatively inexpensive Hotel California and Hotel Augusta.
If you're looking for a good value and don't mind being a bit outside of the center of things, a great option is a number of the family-run pensions geared to all tastes and budgets, which are found in the residential districts: such as Schöneberg and Kreuzberg, where the annual March Music and May Day Riot celebrations take place; or Wilmersdorf and Tiergarten, best known for the famous Love Parade and a number of hip clubs. Berlin's public transportation system is superb, reliable, and runs all through the night.
When economy takes precedence over ambiance, there are a large number of hotels around Berlin's three airports. The Mercure Airport Hotel Berlin Tegel and the Estrel Hotel are some places to check out. And if backpacking is how you're planning to see the city, hostels have sprung up all over Berlin. The most famous hostel is Fabrik in Kreuzberg, the first one to open, but there are plenty of ever more trendy (but equally inexpensive) places to crash.
The hallmarks of Berlin's hotels, like its citizens, are diversity and variety. Visitors to this wonderfully eclectic city are bound to find precisely what they're looking for.
