I stayed at the Orange Hotel Confucian Temple for 3 nights. The hotel is very clean and the rooms are very comfortable. The staff were very polite and although some did not speak english they really tried to help out. I found the customer service at the hotel to be some of the best I have seen in China, even better than some 5 star hotels I have stayed before. The best part about the hotel is the location since it is walking distance to many of Nanjing tourists sites (Confucius Temple, Bailuzhou park, Zhonghua gate, Taiping heavenly Kingdom museum, etc.).
The breakfast is 10 yuan but don't waste your time and money, for 25 yuan you can have a great western style breakfast at the restaurant which is located west of the hotel just before the bridge 1 minute walking distance from the hotel. (They make a delicious cappuccino too!)
