Thank you for the feedback, its unfortunate you felt too cold in the room. I assure you the windows do close it was just a matter of getting in touch with me if you had any issues. We could also have provided a thicker duvet had you needed it.
The room size is faithful to the pictures. It has space for a large desk, a king sized bed, a piano and still space to move around. What extra space would you have liked to have?
With regards to cleaning I'd be curious to know where you thought it was dusty, I paid a professional cleaner to do the work so if it hadn't been done to a high standard its useful for me to know!
