It is really noisy there. The toilets sound like a jet engine taking off, if you're facing the pool, you will hear every single person down there till midnight, inside and outside walls offer no soundproofing. Strangely enough, after reading other threads about this, I figured I could just leave the bath fan running to block out the noise, but the bath fan is the quietest thing in the whole room and has a timer on it. Can't even imagine what it would've have been like had there been people staying in the room next to us.
I didn't even flush the toilet too late at night just out of consideration for those in the floors below me.
