What is the man’s problem?

M: Excuse me. Could you tell me the way to the museum, please?
W: Oh, yes. Just go straight until you reach a crossroad, then turn left and go on walking to the second crossroad and then turn right and you’ II see a 7-storey building. The museum you said is down in the basement of the building. You won’t miss it.
M: Thanks a lot. Is it very far from here?
W: No, it’s only a couple of blocks away. It’s about a ten-minute walk.
