An upscale hotel in South Korea has issued an apology after being notified that people on the street could see into the women’s sauna area inside their hotel.

The Grand Josun Jeju Hill suite issued the apology on their website on February 12th, after a blogger noticed the mistake while spending his honeymoon at the hotel.

According to the report, the blog reported that the sauna’s blinds had been up for part of the day, making it possible for anyone walking by the hotel to see into the women’s sauna area.

“I found out that I was able to see inside the sauna from outside. I could see the thermometer inside the sauna through the windows. We could see the inside of the showers and bathrooms from outside, from the hotel entrance, walk path, car park and from even the hotel balconies,” the blogger wrote.

“My wife and I were shocked to find this out. The thought that we might have used bathrooms and showers in front of many people gives me chills and we’re getting therapy treatment.”

In the statement from the hotel, they apologized for the incident and said they are working on a fix:

“We’re deeply sorry for causing any inconveniences to our customers in using some facilities at the women’s sauna at the Grand Josun Jeju Hill suite for missing mirror coating for some windows and operating the blinds,” the statement read.

“The sauna’s operation has been suspended and we’re closely checking deficiencies and taking immediate action to correct them.”

The hotel further explained that there is a special mirrored coating on the windows that makes it impossible for people on the street to see through the window during the day, however, during the evening hours, the coating is ineffective, which is why the blinds are supposed to come down.

Other guest have since contacted the police who have launched an investigation to see if anyone has been exposed.

According to the agency, they are going through CCTV footage to determine if anyone took illicit pictures or videos from outside.
