Another reason the hotel I wanted to go to and the star rating was low was because the bathroom smell was too strong. Since it was newly built, I didn't use it much, so I was told it would go away when I used water, but it didn't go away throughout my stay. I get some air freshener and spray it every time I enter. It wasn't just a simple estuary smell, but a strong ammonia smell. I would like to contact a professional as soon as possible to resolve the problem. For your information, the same smell occurred in my house after installing a new toilet, and it didn't go away even after reinstallation. In the end, I called a professional engineer from the toilet company to solve the problem. There is a hole in the back of the toilet, so if you close the door and turn on the exhaust fan, the smell comes out even more. When I plugged the hole with silicone, it disappeared. Please note.At this hotel, when I checked in, the bathroom door was closed and the exhaust fan was on, but when I opened the door, the smell was so strong that I fainted. I sprayed air freshener, opened the door, and ventilated the room, but instead turned off the fan and closed the bathroom door. The smell came out, but it wasn't as bad as the first time. This is why I think it may be a similar problem to my previous house.And the cleaning condition was a bit poor. The area around the coffee pot must have been cleaned up, so there were torn bags of coffee and tea, and there was also an empty water tank. The bedding wasn't washed well, but there was too much dust, possibly due to storage issues.Still, it was nice that the cypress bathtub on the terrace was large and had good hot water. You must bring a swimsuit. Slightly visible from the next room. When you stand up, you can see it from the hotel across the street.Since it was a shared building with an officetel, delivery was also convenient as it came right to the door.
