Martina’s place are very comfortable and good for families and a group of friends. If you are coming by car it is so nice that you can just park in front of the apartment. It takes 20 minutes to walk to piazza del popolo and 40 minutes to trevi fountain. And are very close to museum’s and the park. But you can get a taxi to almost every were in the city for about 15 €. Very easy. So I will highly recommend this place if you come by car.
