Most of the company's customers are young, adaptable and practical individuals who don't like crowded living spaces and prefer to store away off-season clothes.

"It's a very efficient and modern lifestyle. We target a specific group of people. Self storage is a lifestyle product. You just use it for two or three weeks to solve temporary needs. Ultimately, this is a luxury," he said.
