First, the receptionists are rude. The staff was not helpful in arranging rooms. We said it would be better if three rooms can be on the same floor and not on the ground floor but the staff wasn't listening and busy on his own stuff, and soon he gave us 3 rooms on separate floors and claimed that it was our problem instead.
He said they are fully booked. Then few minutes later, he said there are one on the fifth floor. He said he got no more rooms on upper floors and said we should request it at the moment we book the hotel, and not willing to change room later on if there's room available upstairs, or else we be charged for the cleaning fee of 23€. At last, we got one on the ground floor, one on first floor and one on the fifth floor.
Second, when we finally got the room keys, we found there is no air conditioner but "air refresher". The room temperature keeps remaining 27C. Moreover, one of our three rooms have problem on electricity. The receptionist failed to send technician to help and he restarted the main button. But soon the all electricity was gone every five minutes, which was unacceptable to be stay for even one night. The receptionist asked us to come for checking every time the electricity broke down even at midnight. It is impossible for us to go in and out all night. Therefore, we asked for changing room, however, the staff rejected and claimed that the room was in normal condition the day before and said foul language at us.
