We stayed here with our older daughter while visiting our younger daughter who was working in the city for a year. We stayed for 4 nights, ate breakfast there every morning and dined there for all but one night as we found the food so good. It's not the cheapest hotel around, but the rooms and facilities are superb and the staff very helpful.
As well as good restaurant facilities, the hotel also has an excellent gym and swimming pool. Beware, everyone, no exceptions, has to wear a swimming cap to use the pool - they will happily sell you one!
Changsha will never be the most interesting tourist city in China, and like many Chinese cities the pollution levels mean the weather is often murky, but the Yuelu Academy is well worth a visit, and a walk up the nearby "mountain" is pleasant, with the option of a chairlift if you don't fancy walking both ways.
