The most central and most expensive area magnets the most of the tourism in Budapest. Almost everyone who visited Budapest have seen Váci utca as well, or walked around the Duna-korzó. The center is definitely the Deák square, from here you can get to Vörösmarty square, then down to the south you can walk down on Váci street or on the paralel Korzó until the Market Hall, then upon Muzeum körútNational Museum. Next to Astoria there is the biggest public-open Synagogue of Europe with the museum of the local jewish community. Back to Deák tér, then up to north there lies the St. Stephen's Basilica, holds the 'Holy Right Fist' relic, which is of St. Stephen, the first king of Hungary, who ruled the country between 997-1038. You can get a nice sight from the tower, or take a look in the treasury which is small, but more ancient relics could be fund there.
towards on north you can find the Parliament with the Royal Crown, or on north-east you can get to the City Park along Andrássy Boulevard.
