I stayed at the Westin during my visit to Shenzhen to attend a summit. The stay was comfortable as were the rooms. The room was clean and had modern amenities. I was happy with the service from the staff. Well located, so that I could walk around the shopping area on my own. At times, I faced some problem due to the language barrier but a lot of the staff could speak English.
There is free wi-fi access throughout the hotel which was a big boon unlike most hotels in the West.
