I was in a Shenzhen for a short trip. The rooms were comfortable and clean. The cleaning staff were extremely helpful and extremely hard working. The front desk staff were politeful and tried to be very helpful, however I'm not sure they are used to dealing with foreign travellers. They struggled to correctly input all of my information and it took 40 minutes to check in on an uncomfortable summers day. I really appreciate their efforts, and expects this was perhaps just due to not having many foreign visitors. Otherwise the hotel was excellent, comfortable, had lovely workers and is very central to Shenzhen.
