Lia was very helpful with arrangements from and to the airport, booked a taxi for us for a good price and always answered messages quickly.
Apartment is very functional, located in testaccio with good local restaurants and grocery shops nearby. Perfect for a "local" stay in Rome.
There is a buss stop for busses that go to the city centre right at the door. Uber also works perfectly, rides cost around 12euros to the main attractions. If you prefer to walk the attractions are a 30-40 minute walk away. Would recommend!
