Casa Di Santa Brigida

From their website: Piazza Farnese, bordering with Via Giulia, is one of the most suggestive corners of Rome. It is situated in the heart of the historical centre of the City, close to the famous Campo de’ Fiori, a few minutes’ walk from Saint Peter’s Basilica, Castel Sant’Angelo, the Janiculum, the Roman Form and the Capitol. The House of Saint Bridget, a splendid XV century building, houses people of all nationalities, creed and age. In the first floor of the House one can visit the three rooms where Saint Bridget lived and died. A big library, a sunroof and especially the welcoming familiar atmosphere render the House an ideal place where to spend a pleasant stay. The services in the rooms include a bath or a shower, telephone and central heating. Board: Full-board, half-board or bed and breakfast. The House is open all the year round and is not equipped for disabled guests.

More info and some other convents they run (that I haven’t seen first hand) are described here.
