Romania is a European country about in the middle. you'll be glad that crime is extremely low here so you don't have to worry if you take a solo vacation on your own, the cost of hotels is extremely reasonable as well. there aren't as many chain ones but the local ones are fairly priced ins.
 trivia fact about Romania is Dracula castle or bram castle is thought to be the inspiration for Dracula! you can tour the castle as well, check it out, maybe it;ll inspire you to buy a book as well!
 Romania is near Germany and other countries so Dracula castle isn't the only castle. it's one of a billion (I'm adding slight exaggeration of course) so rest assured, if you can't make it to see this master piece, there's shore to be a castle in visiting range near you.
 Aside from the castles there tons and tons of forest to explore, lakes to hike around, and small villages with locals to meet.
