Per one customer who booked the Slovenia in One Day: Lake Bled, Postojna Cave and Predjama Castle tour, "Nina was an amazing tour guide who shared her knowledge and love of Slovenia freely and enthusiastically. She was an excellent driver and we loved listening to all her stories between our four stops. All of the places listed are excellent but we especially enjoyed the caves. They were mind-blowing. I'd definitely recommend this tour."
