MGL : Choi Do Kyung's family home in Pyeongchang-dong, Jongno-gu

From this picture we can guess, this place must be the Choi family's home or Mansion

Do Kyung (Park Si Hoo's character) and his parents

And the location from instagram located it as ...

" 종로구 평창동 "

Pyeongchang-Dong, Jongno-gu

From Wikipedia...

Pyeongchang-dong means neighbouhood of Jongno-gu in Seoul, South Korea.

Sometimes called the "Beverly Hills" of Seoul, due to it being a preferred residential location 

for Korean celebrities, it still remains a common location used in Korean films and television. 

It is unusual to most communities in Seoul, in that it is nestled in the Bugak Mountains, 

being surrounded on almost all sides, having the feeling of a wooded resort-like suburb. 

Many multi-story American style homes fill the community, even though being 

primarily mountainous, with roads as steep as San Francisco.

Later I found the location of this place!

Yes, it was shooting location from other dramas before

This is the picture from " My Golden life " crew took yesterday

And this is the picture from a K-drama fan blog,
who did her observation long before me, thank you!

Now let's take a look and compare them

1. From " MGL " crews

2. From Managerhyung blog

You will spot at least 3 things that exactly the same

1. The plaque on the wall

2. Customized gate 

3. The driveway

(We can ignore the decoration in the front, they are movable)

Now, after we're sure this place is right!

Here come the address!^^

227 Pyeongchang 6-gil, 

Pyeongchang-dong, Jongno-gu, Seoul

But better to leave the real owner of this house alone, 

You won't find your Choi Do Kyung there anyway!^^
