The apartment is as on the pictures. Clean and functional with a little added charm, in particular the balcony and back yard. It's functionality and location was perfect for me, working at the University La Sapienza for four weeks. The neighbourhood is very charming and the restaurant downstairs can be recommended.
It is clear that this is a rental apartment and not a place someone lives, so if you are looking for a homey place you might want something else. It is about 20 minutes walk from Termini. The hosts were easy to communicate with and responded swiftly to any question and concern.
