Although the first contact is Greta, the actual host is Pietro in Rome. Both of them are very helpful. Pietro is a lovely man who waited for us late at night for checking-in, and took his time to make sure that we understood all the details of the apartment.
The apartment is as showed in the pictures: Stunning and clean. And also the views are amazing, with direct sight to San Pietro and Piazza del Popolo.
It is a perfect apartment to stay in Rome for a few days, at walking distance to any attraction in the city.
I highly recommend this place.
