In October 1819, Shelley rented an apartment in Madame du Plantis's house, the Palazzo Marini at 4395 Via Valfonda. Here, he produced "Ode to the West Wind,' "Prometheus Unbound," and Percy Florence Shelley.  It was not a totally happy time: in April 1819, Shelley came upon a devastating Quarterly Review article by John Taylor Coleridge purporting to review The Revolt of Islam, but actually mounting a personal attack on its author--Coleridge damned Shelley as a plagiarist heretic with an unhealthy interest in incest.  The winter cold of Florence resulted in a persistent rheumatic pain in his side which forced him to cancel travel plans to Livorno.  Yet the birth of Percy Florence brought Mary out of the depression she had endured since the death of William in Rome, Claire returned to her singing lessons and a crowded social calendar, and Shelley wandered happily through the Uffizi gallery.

The Palazzo Marini faces what is now the Santa Maria Novella railway station, midway between  Plaza Adua and Via Nazionale.

It features an interior courtyard and several charming fountains.
