"I don’t understand how a hotel will not allow guests to control the temperature of their rooms. The air conditioning system is turned off and you’re not allow d to cool your room.
So you do not get a good sleep because you’re hot all night. Can’t open windows, too noisy outside"
Sightseeing doesn't have to be expensive. You if want to get outdoors, try a visit to Hefei Botanical Garden or make a stop at attractions like Hefei Shushan Martyrs. Don't forget to plan a visit to Yangtze.
