I visited many years ago. If you think its cheap now, at the time I took out a group of 12 people for dinner, and the tab, including drinks and violin music, came to like $25 total! I saw many of the sites you did, and I agree its beautiful. Our host made sure to point out certain fragrant trees that only grow in Budapest. (not sure if he was BS'ing us there). Only the air pollution and resulting blackened buildings detracted from the historic architecture. Maybe that has changed. Our biggest challenge was navigating Hungary with a road map printed in German. Wow, the Germans like to rename everything, ie, Lake Balaton becomes Plattensee!
