We had only been to Rome once before, the area of Trastevere was new to us. It is removed from the business of the centre of Rome which is really nice. The apartment is close to some great restaurants and easy to walk to get a taxi to take you to the centre of Rome or any attractions. This is a clean, simple apartment, priced well with a great host, and sometimes that's all you need! Communication with Marco was great and he helped us arranging for taxi to the airport from the apartment the morning of our departure.
If you stay here, definitely explore the restaurants that are very close to the apartment. The restaurants in the centre of Trastevere are REALLY touristy. Have a plan or itinerary for where you want to go, grab a taxi and enjoy!
