For those familiar with the Sindaebang and Sangdo areas, what do you think of this?

‌

I am looking for an apartment under 1.5 billion KRW along Line 7.
It seems like there are some decent options around Sindaebang or Jangseungbaegi Station?
However, it's a bit disappointing that the surrounding area is mostly composed of villa neighborhoods.
What is the atmosphere or general standard of this area like?
