The Keats - Shelley House

This modest house at the foot of the Spanish Steps is where John Keats spent his final months and died of tuberculosis at just 25, and it has been maintained since as a memorial library and museum dedicated to Keats, Shelley, Byron, and their contemporaries. The room where Keats died, along with letters, manuscripts, and death masks, gives the museum an intimate, literary-pilgrimage quality distinct from Rome's grand art institutions.

A 4.6 rating and the highest hidden-gem score among comparable central-Rome sites suggest it's genuinely under-visited relative to its significance, appealing strongly to literature enthusiasts who seek it out deliberately. Its small scale and modest ticket price make it an easy, quick addition to a Spanish Steps visit for the right traveler.
