I strongly recommend the self-service apartment chain in Dingwangtai. It is not far from the pedestrian street. It only takes more than a hundred nights, and the environment is good. Last week, two foreign friends of mine came to Changsha, and I made a reservation for them. They are very satisfied. If you have a student ID card, you can get a 28% discount. At Dingwangtai, the boss is also very good. His name is Gao Wei. Let me tell you his QQ, 3437 165438.
If you don't like it, there seems to be a self-service apartment hotel in Wuyi Square, which will be more expensive.
I recommend the one above. Convenient transportation and good environment.
It's easy to find in Dingwangtai Medical Meihui Modern City.
