The downside of staying at Saturn Hotel is the shower area, because the shower area is not separated by glass, so when taking a shower, all the water splashes onto the sink floor, finally the floor becomes flooded and slippery, which can make us slip/fall, because the toilet ceramic is a slippery model, rougher ceramic should be chosen, so we can shower more safely, and the toilet does not have an exhaust fan, so the floor is slow to dry.
