I wouldn't even know where to start. Definitely from the pillows. Since I don't like the Japanese style (with grains of plastic inside and flat) cause I feel it hard, I asked if it was possible to have another softer and taller pillow. The staff then took another identical pillow and while stuffing it into the pillowcase, let it touch the floor. When I pointed this out to him, the attendant didn't change the pillowcase but simply gave it a slap with his hands to clean it up.
In the evening I couldn't use the Wi-Fi as the signal was very weak.
It was difficult to sleep at night due to the hard pillows and the walls that were thin like paper. At 5:30 the sound of an alarm from the next door room woke me up and it went for over 10 minutes because of the snooze. Around 6:00 AM a middle school baseball team was very noisy outside my room keeping me awake for a long time. And finally, the craziest thing that ever happened to me: a customer opened my room door with his key card at 7:00 AM.
I asked at reception how this could happen and they told me that the keys open every door. So, is it that easy to get into any room? In the end I asked for a refund for one night and it was granted. I honestly don't recommend it even to my worst enemy.
