Got free upgrade. The room is good and reception is friendly. However, the operators are rude and not responding. Requested three times and waited an hour to get a new towel. The air conditioner is not working the next morning. Called the operator. She kept asking if the windows are opened even I confirmed they are closed. No one came to have a look after I called few times until I came to the reception and reported it. Unfortunately, the ac is not fixed for the whole morning and afternoon.
