In the condominium near the port of Kaohsiung, you could watch the view of one of the most busy port in the world from the rooftop. It's about 5~10 min from here to Kaohsiung airport, and 40 min to the downtown by bus and MRT. Have good time!
There's a bus stop, and it takes about 5min for walking to there. "Red 6" is the line to the MRT station "Caoya." And it takes 40 min to the downtown.
