The check-in was really uncomplicated. Liviana's friend picked us after we called her (number was given - well organised) and got us to the apartment. The room was VERY clean (it was also cleaned every day) and big. The location is very central and close to public transport. But, nightlife is half an hour away by bus (Uber is very expensive in Rome).
We enjoyed to stay in this apartment. Unfortunately we had to go home one night earlier. It was no problem to get the refund.
