How about Qingdao Chengyang Detai Hotel? Did you find it?

The service in this hotel is the best hotel I have ever stayed in. Although it is a four-star hotel, it has a five-star service attitude. Especially the front desk, it is super warm and feels at home. Our team originally planned to stay for one day, because they were moved by their enthusiasm and service attitude, and later extended their stay for two days. This hotel is highly recommended.
