What did Jerome imagine about Hampton Court? What were the reasons for his changing his mind about the pleasures of living in Hampton Court?

Jerome imagined Hampton Court as peaceful during the day and dull and depressing at night. 

I’ve often thought I should like to live at Hampton Court.  It looks so peaceful and so quiet, and it is such a dear old place to ramble round in the early morning before many people are about.

And then he changed his mind......

But, there, I don’t suppose I should really care for it when it came to actual practice.  It would be so ghastly dull and depressing in the evening, when your lamp cast uncanny shadows on the panelled walls, and the echo of distant feet rang through the cold stone corridors, and now drew nearer, and now died away, and all was death-like silence, save the beating of one’s own heart.
