Claudia is a very hospitable person and offered help concerning everything (especially the somewhat messy Roman public transport). We could always approach her and she was very welcoming.
The charming apartment is very neat and nicely furnished and the room quite large and we could use kitchen and bathroom whenever we wanted.
There are all the necessary shops in the vicinity, especially the least expensive supermarket we saw in the whole of Rome, and a bus stop right across the street and a tram stop 5 minutes away. You'll probably want to use these as the apartment is about half an hour from the city centre by public transport. After some initial problems, finding our way in the public transport network became easier, but don't be surprised if trams don't arrive or buses are late.
All in all we had an amazing stay at Claudia's apartment and can recommend it highly. We'd love to stay there again on a future visit to Rome! Thank you for everything!
