I leave an honest review.It is close to the outskirts of Seoul, about an hour away, but it is located halfway up the mountain, so it is very difficult to get there by 45-seater bus. A traffic map is required when going up and down.The air conditioner does not work because the air conditioner is not maintained.I stayed in a very hot accommodation with a perceived temperature of 42 degrees for 3 days and 2 nights.There are a lot of insects, but since this is a mountain, it seems inevitable.The biggest problem was that the water was shut off a total of 5 times, making it impossible to wash while showering. (I hope it gets fixed)Because the slope is high, falling on the unpaved road can result in serious injury.Due to the poor environment inside the accommodation, an accident occurred where the bathroom door did not open, resulting in an incident where the bathroom door was broken.Separate meal times are not set for each team, so it is crowded. Rice is generally delicious.There is a set swimming time, but it is very generous.It was optimized for a summer retreat, but if there were no accidents such as water outage, no air conditioning, or not being able to get out of the bathroom, the accommodation would be generally satisfactory. I wish it could be managed a little better.I couldn't find a place to stay because I didn't have time, but if this is the only place I can do it, I would definitely go there if I have enough time and can find a better place to stay.
