Actually, believe it or not, he lived in Bucharest and, for a long, long time

in... Budapest as the honored guest (private cell, no outside view and shackles

attached to walls) of the Hungarian King who was... Romanian (from Illyria,

nonetheless!) His palace in Bucharest was obliterated by Dracula II (aka

Ceausescu) to make room for a modern monstrosity, the People's Palace.

He also stayed in Targoviste, but never at Bran which he tried to sack twice

with not much success (although he burned the crap out of the surroundings).

He was burried near Bucharest, Monastery Snagov, but, when the grave was opened

in the 20's, it was empty! Oooooooooooooo...

Have a good trip and bring along some garlic and a wooden cross... just in

case!(US dollars will also help!)
