I want to know the answer to the following question:
The elevator located at the Casco Viejo station in the Bilbao Metro is also used for what?
All the background I'm provided with is that "For example, there is a 3-station underground public elevator in Yalta, Ukraine, which takes passengers from the top of a hill above the Black Sea on which hotels are perched, to a tunnel located on the beach below.". Is that enough to answer the question?
