Courtyard Hotels in Luton

I booked a room from Ctrip, because I had a flight to Larnaca at 10:30 today morning, and it was better to live in one Hotel near London Luton airport, I choose this Hotel on Ctrip website. I took a train in Cardiff to London, than transfered to Luton airport by train. It was a long time to arrive the Hotel around 12 O'clock in the night today. There was a young woman in the receiption. I was harried to go to toilat, and asked her where is the toilat, she said there is no toilat. I am very angry for her reply. I told her I will check in later after I went to toilat. The manager came and show me where toilat is. Today morning at 7 O'clock, I Check out at the same place, and met the same woman. She said I had bought one Water and one Chocolate wnen I Checked in. Of course I need to pay, how much please? After she Checked and said : 95 Pound. It's crazy: one Water plus one Chocolate cast 95 Pound! I have paid for my room before I arrive! The same manager came again and check. Than told me 5 Pound I need to pay. This Hotel belong Mariot Group, I don't know I met such low employee in their Hotel. Very low and stupid. I decide I never live in this Hotel and talk about my experience to my friends.
