As other reviewers have said this place is a little dark and humid as it is underground, however this was not a large issue for us. The host had put a dehumidifier in the apartment for us.
Be sure to ask the host where the escalators near the apartment are! If you use then you can get to and from the metro in about 10 minutes, which makes this location pretty great.
It's in a great area that felt safe, had a great view, and plenty of restaurants, grocery stores, and transportation near by.
The apartment was very clean and could comfortably sleep 6 (double bed, 2 bunk beds, double sofa bed).
