Natalia was a great and responsive host. We kept in touch via Whatsapp which worked out great. She helped to arrange a private car to pick me up from the airport late in the evening, and was waiting past midnight for me to check in, which was very much appreciated. At the end she was also kind enough to agree to a late checkout as Our train did not leave until later in the afternoon.
The apartment was clean and exactly as described. It was a bit too cold for us to use the terrace much by the end of the trip, but it was a lovely space for those who are less afraid of the cold, and definitely a huge plus during the warmer months (To be fair we are a little afraid of the cold as we live in the tropics - northerners should be fine!)
The apartment is facing the back, so is relatively quiet for a city apartment, which is great for resting. Small gripe would be that some nights we could hear the neighbours watching their TV, and/speaking rather loudly till past midnight. But that is to be expected anywhere, I suppose.
Overall, a great experience, and we would definitely not hesitate to return to Natalia's next time we are in Rome and need a larger family space, especially from Spring through Fall!
