The problem with 1 is that books should not be exposed to that much sunlight, but it does look rather pleasant.

I like the ones that are very secluded and where you can't be seen from the outside - but I also think that the lighting seems to be a bit poor in many of those. Not much of a reading nook if you can't see the book.

Btw, the numbers change because they are based on people's votes... the one with the too-small door is now number 3 rather than 4.
