Travel time from Kunming East Bus Station to Mulan Guest House. Visiting there soon.

How long would it take a taxi to get from the East Bus Station to the Mulan Guest House on 8-4 villa Xiyuan Road?
Trying to find the fastest and best route from the airport. Thought taking the subway to the East Bus Station and then a taxi may save time. What would the time and cost be to take a taxi from the airport to the Mulan Guest House, 8-4 villa Xiyuan Road? Thanks!!
