As a Transylvanian local, I have to admit I hadn't visited Bran Castle in ages. It took my friend @NomadicHamwi of @StellarOrg traveling from the US & eager to explore the legendary 'Dracula's Castle' to get me there again. The dramatic views, the medieval charm, the myths... we had so much fun rediscovering it together!
