Hello Kernessa! Many guests ask me to put the shower curtain for the bathroom. The space is small and you can not put a box. I am opposed to the tent because it always sticks to the skin and so it is unhygienic. I never go to places where I find the shower curtain. Maybe it's my paranoid, but I think it's better personal hygiene.
The bathroom is one room with toilet and sink and shower as all bathrooms Italian. In Italy you'll never find the toilet separate from the shower and the sink, this is our custom. But we have the use of the bidet that guarantees excellent hygiene.
It has been a pleasure to host you and recommend places of Tuscana. Hope to see you soon and thank you for your kindness. :)
