Berlin is the scene of frequent international trade fairs, conferences, and festivals, and during these times, vacancies in the city will be hard to find. The greatest concentration of hotels, from the cheapest digs to the most expensive, lies in the center near the Kurfürstendamm (Ku'Damm), the main boulevard of western Berlin. Most good-value pensions and small hotels are in the western part of the city; note that many such accommodations are in older buildings where plumbing is rarely state of the art.
The business convention crowd still anchors primarily in the west, as do the hordes of summer visitors on whirlwind tours of Europe. Eastern Berlin often attracts Germans from other parts of the country who want a glimpse of the Berlin that was shut away behind the Wall for so long. The eastern sector still doesn't have the visitor structure and facilities of the west, although several first-class and deluxe hotels have opened there, notably the Grand, Adlon, and Hilton.
Travelers can also head for hotels in Grunewald, close to nature in the Grunewald Forest, or Charlottenburg, near Olympic Park. If you like biking, jogging, and breathing fresh air and don't mind the commute into central Berlin for shopping and attractions, you'll enjoy both these areas.
Tegel Airport is only 20 minutes from Berlin by taxi, but if you have a very early departure or late arrival, and want the added security of an airport hotel, you can check into Mercure Airport Hotel Berlin Tegel, Kurt-Schumacher-Damm 202, 13405 Orsteil-Reinickendorf (tel. 030/41060; fax 030/4106700). Doubles are medium-size and furnished in standard motel-chain format. The rate for a double is 140€ ($224). There's also a restaurant on-site, plus a free shuttle service that runs back and forth between the hotel and airport. American Express, Diners Club, MasterCard, and Visa are accepted.
