My husband, his mother, and I visited Rome in February 2020 and wanted a quiet place in a good location walking distance to major sites we planned to see (especially Vatican City, which was about 15 mins beautiful, safe walk away). With Cristina's place we got exactly what we wanted and expected. The apartment was clean, looked better than the photos, and was in a great location around the corner from the Spanish steps. Cristina was responsive and helpful from day 1. She arranged pickup to and from the airport for us in a private, air-conditioned van with bottled water at a great price compared to taking a taxi. At the apartment she had a map for us to use and pointed out key spots. There were fresh roses in the kitchen when we arrived and Cristina met us with the key. Checking out was simple, and Cristina as well as the private drivers were easy to reach by text on Whatsapp. Lots of shops and restaurants and a grocery store really close by, not too touristy. Felt very safe walking around after dark. The restaurant below the apartment is good but branch out a little and you'll find even better little gems to eat at nearby. No problem communicating in English with nearby shops, etc.
What most surprised me was how quiet the apartment was, despite being in the heart of the old city. For three people, the rooms and bathrooms were the right amount of space (small but well-appointed and maintained). Only drawback is that there is no elevator and we had to climb four flights of stairs to and from the apartment--not a problem for me and my husband but a bit of a challenge for my older mother-in-law. All in all, though, we would happily stay here again. Highly recommend.
