Hamburg is an expensive city with an abundance of first-class hotels but a limited number of budget accommodations, especially in the center of the city. During a busy convention period, you may have trouble finding a room. A department within Hamburg's Tourismus Centrale (Tourist Information Office), in the Hauptbahnhof, at Kirchenallee in the Wandelhalle (tel. 040/30051300; fax 040/30051333), can book accommodations. Rooms from more than 200 hotels in all price categories are available. There's a fee of 4€ ($6.40) per reservation. You can use this agency on a last-minute basis, but no more than 7 days in advance of the time you'll need the room. Hotel-booking desks can also be found at the airport in Arrival Hall A.
