It's nearly impossible to imagine a better location in Rome!! I love this place! Besides, you are at walking distance (10-20 min) from Castel Sant'Angelo, Fontana di Trevi, Piazza si Spagna, Piazza Venezia, Trastevere, etc.
The view from three windows to the Pantheon and Piazza della Rotonda is unbelievable!! In comparison with this magnificence, one can simply disregard minor inconveniences (a very steep staircase, a kitchenette in the bedroom, noise outside).
Maria and Emiliano are indeed very friendly. It was very easy to communicate with them.
Highly recommended!
