Broadgate溜冰场

I ordered superior room from 28/4 to 4/5. So far, the staffs were very helpful and friendly that I have ever seen. However, the assigned room was not like the room’s description posted at their Langham hotel official website. They mention that the hotel room features large picture windows, plenty of natural daylight, and a gorgeous courtyard or city view. But, my room did not have any view. It has faced to so dirty roof top. I never open the window during my holiday. I was very disappointed I paid so much money for about 6 nights but resulted I got the room with such bad view. Could you please check if they provided the incorrect room type for me?
