Stayed there with my wife and our three teenage kids. Rented all three apartments. Everything was as advertised. Plenty of space, clean, and A/C in all rooms. Yes, there is a hill! And no, it is not recommended for people with mobility issues. That said, I broke my leg and tore my MCL five weeks before our arrival and we decided to keep the reservation anyway. I managed to make it up and down the hill many times on my crutches (there was a taxi strike for two days…but when the taxis were running they would drive us to the top). I wouldn’t recommend climbing up and down the hill to others on crutches but it was manageable for me (48 y/o male). Federico and his team were very attentive and responsive to all our needs and questions, helping to arrange transport to and from Roma Termini on our arrival and departure days. Would definitely recommend their place to others!
