This is a professionally-run listing and Alessandra and her team are very kind, organized, responsive and punctual and are available at any time of the day by phone or email.
The apartment on Via Del Babuino is clean, modern, very spacious and is located in my favourite area of Rome: many shops and restaurants but more locals than tourists, close to the metro, and right beside Piazza di Spagna.
We will absolutely stay here again next time we are in Rome.
