Greetings! I would like to recommend guide Ivan Goncharenko to all travelers, he offers Slovenia private tours https://slovenianguide.com/private-tours-slovenia/ including nearby countries. With it, you can look inside the culture and history of Slovenia, see incredible places: parks, caves, castles. Price: 230-280 euros for a group of up to 7 guests. I think this is a fair price for such an experience.
