We enjoyed our stay at Valentina's place. It was exactly as described and very accommodating of our young family (children aged 5 and 2). The travel cot was clean and there was also a highchair for our son. There was also a lift to the first floor which was helpful with the pushchair, although there was still a step down from the lift to the floor, so not step free for wheelchairs if needed. The apartment was large and well-appointed and quiet. We had no noise disturbances from neighbours.
The apartment is a couple of minutes walk from two different metro stops and a very good supermarket (24 hour). It is also about 10 minutes walk from the main train station.
The host was very attentive - we were met exactly on time and any problems were resolved quickly, such as when the hairdryer blew up.
Overall we had a great time in Rome and would highly recommend the apartment and host.
