This is an interesting experience for me. When I arrived at the entrance, I thought that I was in a wrong place. I asked if I could cancel the reservation. The girls at the front desk (actually more like an one-concept regular office) explained that the rooms were spacious, with 54 square meters. Hearing that, I wanted to see a room. I was taken to the 2nd floor and to my surprise, the room shown to me was really stylish and spacious. It appeared very clean as well. At that, I decided to stay at the hotel. Two other reasons that I did not want to cancel the reservation were: 1) too late to find another place; and 2) it would be a fight with the hotel as its cancellation policy that I needed to cancel on the day before.
My stay there was overall OK, but there are three things worth mentioning: 1) the hotel is very close to a huge park and Xujia Hui Center; 2) the internet was painfully slow; and 3) the breakfast was not up to the standard even though the chef was very nice. Later a friend of mine told me that the Heng Shan Road area is also well regarded in Shanghai.
Overall, this is a hotel with great potential, but there are some limits. If the limitations are improved by the owner, I will definitely go back to the hotel.
