Does my sentence make sense?

Toritoribe said:

In a situation you want to emphasize the location the agent is at or the starting point of the movement, yes, 階段の上から下りる makes sense, but 階段の上からに下りる is ungrammatical. If you want to say "to go down the stairs", 上から is redundant, and it's OK just 階段を下りる.
