I can't say how good the location is overall, since I ended up not spending any time in Changsha except sleeping - it looked like the hostel was close to a lively walking street, but the hostel itself is in a quiet alley. While it was okay getting there, the hostel was a bit tricky to find, and arriving alone in the late evening was not very comfortable for a female travelers, since you have to pass through a dark and narrow alley.
The room was okay, expected for the price, but the mattress was hard as bricks so I couldn't sleep well, it was too uncomfortable. The lockers for personal items had no lock (or if there was a way to lock the staff didn't tell me), so nowhere to store personal items, making the place unsuitable for a longer stay.
Bathroom has only one sink, one shower and one toilet to be shared between 2 dorms, so the bathroom was not clean when I arrived at night and everywhere was wet, which was very uncomfortable.
