I can only recommend Lillo's apartment to everyone. We were a group of three adults and two small kids (2 and 4 years old) and we enjoyed our stay at Nicolo's. The apartment was easy to find and there was sufficient space to park our rental car in a locked backyard, despite the fact that the car was not small by Roman standards (Ford C-Max). Simona, Nicolo's sister, kindly showed us the apartment and it was a nice surprise to find some fresh fruits and biscuits in the kitchen for a first snack. The apartment is spacious and in a very good condition. The mattresses were a bit too soft for my taste, but this is really just personal preference. The location of the apartment is perfect, we managed to walk to the major sights (St. Peter's cathedral, Spanish steps, Fontana di Trevi, Pantheon etc) even with the two small kids. Lepanto metro station is just around the corner, if someone prefers to use the public transport.

Overall, we had a great stay. If I ever return to Rome with my family, I will definitely choose Lillo's apartment again.
