Location: Within 50 metres of Tumuli Park main entrance.
How to get there: From Tumuli park's main entrance, walk to its public restrooms (left of entrance, if you are facing the entrance). After the public restrooms is a lane. Go down the lane for about 50 meters. Luckywon is on the right.
Alternative way to get to Luckywon: go to Gyeongju's tourist info and ask the very helpful English speaking staff to give you Luckywon's business card and write instructions in Korean for you to show to taxi driver.
Price: We (2 Adults + 1 child) paid 40 Won for one night of an ondol room, TV with attached toilet/shower which came with medium sized towels, soap, shampoo, toothpaste, etc.. The inn also has a kitchen-and-dining room for guests to use. It's a fully equipped kitchen (utensils, cutlery, fridge, etc). The kitchen has several tables for families to eat their meals. There is also free internet and use of computer in this room.
We chose to stay in Gyeongju town instead of being tucked away at the Bormun lake area. This inn was recommended to us by the Tourist Info after the other (famous) inn is full. It turned out to be a blessing in disguise. The host speaks some English. The hostess does not, but she compensated by being very helpful. She did our laundry for us free of charge, dried our clothes, folded them, and then left the whole stack (we had been travelling for many days before we reached Gyeongju) in our ondol room. The host and hostess stayed in the original house, while guest stay in two new extensions built on the left and right wings of this original house. They gave us enough privacy and did not expect us to be part of their family. However, when we needed help and approached them, they were more than happy to help us.
The extension wings which house the ondol rooms/units are brand new and very clean. We are provided with mattresses, pillows to sleep on, and the floor is heated at night.
The location is very convenient. It is between the bus station and train station, and next to Tumuli park's main entrance. There are several restaurants located to the left and right of Tumuli park. Taxis also congregate outside Tumuli park, so we had no difficulty hailing for relatively cheap taxis to anywhere in Gyeongju even as early at 7 am.
As Luckywon is 50 m from the main road, it is very quiet at night.
