We call it the Chicken Shed! Literally it was a totally detached (from the main farmhouse) chicken shed (now a bathroom) with a farrier above (now a bedroom/sitting area). Built around 500 years ago, but restored rather more recently. A compact and bijoux space. 3km from a station, direct line into Florence.
It really is your own space. There is a comportable suspended double bed, and below a coffee/tea station, a small fridge, and sitting area.
