Ana who stays in the apartment is a very nice and accommodating lady and we really enjoyed our stay with her. She only speaks Italian, so communication may be difficult sometimes, but she is patient and we learnt alot from her (get the italian experience :)).
The apartment is well located near the Barbarini Metro station and is at the junction of Quattro Fontane, within walking distance to all the central attractons. Note XX Septtembre is a very long street so it was hard to find the apartment at the start. Breakfast is simple but very adequate. The bed was too springy for us and the water pressure and heat in the bathroom was not adequate (especially on colder nights).
Overall, we enjoyed our stay and our time with Ana and recommend this apartment.
