Assuming that by 'apartment' you mean 'space owned by you that you can do absolutely anything to', then this might be a marginally interesting book for you. I think of 'apartment' as meaning 'space owned by someone else, who will take legal action if I knock-down or erect walls or replace the kitchen appliances'. Given that (not uncommon) meaning of 'apartment', this book is absolutely worthless.
But, let's just it on its own terms. What would we expect from a book like this? Well, I would expect deep insight into the patterns of design for small spaces. I would expect clear exposition of those patterns. I would expect brilliant and informative photography. What the book actually supplies is gushy prose, little if any useful advice, ugly and apparently almost useless apartments, and amateurish photography (the photographer should invest in a polarizing filter, for crying out loud, if he's going to take photos in rooms that have lots of reflective glass).
I read a lot of these high-end design books and I feel confident in saying that this is the worst I've seen in a long time.
