We spent 5 days in march at Marianna's place and I can really recommend it. The interior and the terrace is so lovely and the location is the perfect spot for both sightseeing and nightlife/eat and drink as well! Close to the heart of Trastevere, Vatican, Campo de Fiori 15 minutes walk but the street is not too busy so it is nice to take a break from the city there.
The apartment is perfect for couples. Everything was as in the description and Marianna gave helpful tips and answered to all questions very quick, all organization was perfect. If you consider booking this place, do not hesitate and enjoy :)
