As I checked in, the reception did not give me the wifi password, after I returned to the hotel after 10pm, I called to the front desk and service hotline, no one picked up the phone, I went down to the reception in the next day, I complained to the front desk, they said that they are busy, and ask me to wait, they did not say sorry at all, I felt bad. This is the worst service I have ever had before in the 5 stars hotel.
