I spent 3 in here, for the last night ,I found my room s air conditioner is not working. I wait 2 hours for the warm wind and nothing happened.I called the fronted desk and they said they send somebody check. I wait 30 minutes and nobody come, and I call front desk again and they just let me wait. I wait 30 minutes again. Somebody come to reset the system and he said wait 15-20 minutes, it will be good. Thus, I spend an another hour to wait the warm wind. Actually, nothing changed. I am so cold in room even my parents can fall asleep. I go down stairs to talk to the front desk directly and they say somebody will come again or change the room for us. The fact is NOBODY COME for the whole night. I am so disappointed on their service,cuz they don t care their customers.At the time I checked out, I tell the front desk agency the situation, they don t say sorry or feel apology for that, they just said they will let the manager know and that s it.
