Manuela is a great and friendly host! She was very responsive at all times of the day before booking and during my stay. She is very helpful, gave clear instructions, and was very flexible with the check-in time.
The apartment is located in a very good part of town. It is very close to the Ponte Lungo and Furio Camilo Metro A stops. It is walking distance to San Giovanni/Scala Santa/Santa Croce or even all the way to the city center if you like walking. It is also very close to Caffarella and Appia Antica parks.
Having no elevator might be an issue for others, but it wasn't a problem at all for me. The apartment is very organized and fully functional. The kitchen is well equipped, there's a washer and clothes hanger for laundry, there are extra linens and pillows, bathroom is supplied with extra towels and soap/shampoo. The apartment has anything you need for a short or long stay. I stayed for 8 days and felt right at home!
