Extremehoteldeals.com has a smoking hot deal up right now for the top rated hotel in Yeosu, South Korea. Normally, the MVL hotel retails for roughly 250,000 won per night. Someone must've had a fat finger when posting it up on the Hotelopia website, because rates are currently 1/10 of what they should be at 25,000 won. 1000 won is approximately $1, so in essence, you are getting a $250 room for $25!
One of my parents is originally from the Jeolla province of Korea and the area is known to have some of the best food and beach accommodations in all of South Korea. Having been there several times, I can personally attest that it's a great place for food, drinking and relaxing with friends and family. This area in South Korea is also widely regarded as where most of the swindlers from the Hermit Kingdom hail (entrepreneurism at its finest!) but that's neither here nor there. This is definitely an "off-the-beaten-path" type of booking, but if you're planning on being in Korea or live there, I would sincerely suggest you look into this.
Here are some reviews on Tripadvisor which details the MVL as the #1 rated hotel in Yeosu.
Bonus Tip: Go through topcashback.com's portal to get an additional 7.5% cash back on all bookings through hotelopia. You're already getting a 90% discount, but hey, cash back is cash back! This deal is so great, I booked two weeks for my parents and their friends in May. You can always cancel before the day of your check-in, but I believe there's a $7 cancellation fee. To me, that's totally worth the risk, but your mileage may vary (YMMV) Act quickly if you want to get in on this!
