Sometimes you find a sento that is just so Osaka and really keeping the sento culture alive and Eiwa-yu is definitely one of those. Three floors of baths! You gotta love the stairs—try not to slip! On the bottom floor there is a doughnut shaped walking bath that I was a bit confused about. You can see the water pump in full view also. On the top floor there is great little rotenburo. This place has everything. Highly recommended.
