Casa Guidi is a writer's house museum where Robert and Elizabeth Barrett Browning lived from 1847 to 1861. Their son, Pen, was even born there in 1849! The apartment is now part of The Eton College Collections and managed by the Landmark Trust. You can visit Casa Guidi on Mondays, Wednesdays, and Fridays from April to November for free, but donations are always welcome. It's a cool spot to check out if you're into literary history or just want to soak up some Florence vibes.
