The 19th district of Vienna is located north of the centre (Innere Stadt) on the outskirts of the greater metropolitan area. One of Vienna's largest districts, Döbling's quaint old villages, lush forests, large swathes of vineyards (it is Viennas prime wine cultivating area) and the up-market Cottagenviertel residential suburb also make it one of its most enchanting too. Döbling managed to preserve more of its traditional 19th century flavour than any other district. Hilly, rich in greenery and replete with many magnificent old houses, Döbling is one of the most expensive housing options in Vienna and site of the official residency of the president of Austria. It has its fair share of hospitals, retreats, parks (like the Japanese Setagaya-Park), outdoor swimming pools and old cemeteries. Public barbecues are typical Viennese summer events and Döbling has one of the best in town. The S45 and S50 suburban trains operate in Döbling as do the U6 and U4 underground lines. You can even catch a ship or ferry on the Danube at Nudorf.
