A great feature of The Decameron is that it's easy to read and the chapters are short and largely self contained. It's not one of those books that you need to be in the right head space for, and have a big chunk of time where you can sit down and dig in. I read The Decameron over 6 months or so in random little moments, a chapter sitting on the subway, a chapter during lunch, while laying in bed, etc.

There's apparently a pretty amusing adaptation on Netflix as well.
