Very nice space in a great location. Walking distance to many sites - Basilica di San Clemente is across the street and the Colosseum is a five minute walk. Also quite a few good restaurants and cafes nearby (especially Li Rioni, Luzzi and Caffe L'800). Roberto and Claudia were welcoming and helpful.
Taxi stand is at the bottom of Via di San Giovanni, across from the Colosseum. Also, 24-hour supermarket (Carrefour Express) is a five minute walk away.
