There is a spot along the Danube river, where you can shoot the Buda Castle and the Chain bridge aligned to each other. Unfortunately during my stay in Budapest this spot was almost always blocked by huge river cruise ships. Only one evening I got lucky and had a free sight for about half an hour there, before the next ship arrived.
