I love this book. Although tiny, it features really nice apartments and, best of all, shows their floorplans, so you can figure out for yourself approximately the room sizes. If you are planning on doing renovation to try squeeze the maximum our of your square footage, this is a great book to study beforehand, because it has some really well thought out ideas. If you are having building work done, you might as well do something brilliant for the mess and the money. It is similar to Terance Conran small spaces book, without requiring you to have double height ceiling everywhere like he does (for the mezzanine...).
This have decorating solutions too, but I think it is mostly about bigger changes.
