If you stay, it will be enough. There are four people in a dormitory with a small balcony. There is a public toilet, a water room and a washing machine room on both sides of each floor. Some aunts clean every day, but they can't use electrical appliances. But in fact, according to the accommodation fee, it is worse than the same one. There is no air-conditioned TV, only an electric fan.
Transportation: If you just come to Geng Dan, you will be disappointed, because it is far from the city. After all, it is in Shunyi. But it's really suitable for learning. It takes about one and a half to two hours to get to Dongzhimen by bus. It takes about 20 to 30 minutes to get to Shunyi County. If you want to take the subway, you should go to the county seat or Houshayu (around Kuliushu Island). There is a line 15. Get used to it after a long time.
