There are many guest houses and they are cheaper. Now it's 40 yuan. Living in air conditioning in summer vacation should take about one day in 50 yuan. You can bargain if you stay for a long time. It's very cheap. I have lived in a good environment since the beginning of school. The one I live in seems to be called Xinyi Guest House. The boss is very enthusiastic and comfortable to live in. From Sichuan University to Golden Campus Square, turn right and turn left at the first crossing. You will see more guest houses and a big supermarket, which is very convenient.
