The actress says she loves to "immerse herself in different cultures," reported Female First.
"I don't know (if I can still stay in hostels anonymously), maybe not. But travelling is important to me and I love immersing myself in different cultures.
"The big advantage in staying in hostels is that you get to meet so many people. I like being able to connect to people - it really enriches my way of appreciating the world," Robbie said.
