If you stay in Nanjing, a budget hotel is recommended, which is:
It is at a prime site – in the Confucius Temple area. 168RMB per room. The room is clean and with fast internet connection. I chose the hotel for a friend based on hotel users’ positive review. My friend’s comment after using it? Positive, of course.
Opposite this budget hotel is a five-star “Mandarin Garden Hotel” where you can buy train tickets to anywhere in China for a service charge of 5RMB. Very convenient.
