I booked the apartment for my girlfriend, her mum, sister and friends which they were only girls. The location of the apartment is very safe and quiet at night. Carmen made sure that they had everything and she even offered to book the taxi to go back to the airport due to an early flight. She also kept in touch with the girls if they needed anything. The apartment it's very central just 10 mins away from the Colosseum with metro. The metro was also nearby about 5-10 mins walk and also a supermarket was near.
