It is on the river obviously but you almost can't get there unless you are on a tour boat. The ferry boats do not stop there. I guess you could hire a private boat but make sure he waits for you. But that wouldn't be long there isn't that much to see. If you don't take "a boat tour" then your best bet if to take a tuk tuk but then that presents problems. The last 100 yards is though a slum on foot with twisting alleys. Besides the museum isn't really all that great. There are 4 or 5 and they all look about alike. The odds are you have seen one on TV. So, my advice is, skip it unless it is on your water tour boat.
