The hotel in Nanjing that I wouldn't mind staying for three nights is the Treasure Hotel

The stay experience was really good. First of all, thanks to the warm service of the front desk, Shirley, who provided breakfast and upgraded the room type. Although the hotel is old, it can be seen that it is well maintained, except that the elevator card is a bit unresponsive. The room is very large, about 40 square meters, and I really like the city view from the 40th floor. The sound insulation is also good. The bathroom is separated from the wet and dry areas and there is a bathtub. The stay was very comfortable. The disposable plastic mat for bathing is also free. The breakfast is not bad, everything that should be there is there, and the food and accommodation are quite attentive. Overall, it is a very cost-effective hotel. It will still be the first choice when I come to Nanjing next time.
