Staying at Andrea and Carlotta's apartment was such a treat!! Carlotta met us at the apartment once we arrived and immediately put us at ease and explained the lay of the land. She was extremely gracious and hospitable; there was a book they had made up full of restaurant suggestions, a map in the apartment with locations of their favourite restaurants and business cards for them, and also they provided a laptop and a pre-paid cell phone if we needed to get in touch with them. They arranged both our pick up and drop off at Fiumicino which was so helpful.
The apartment is beautiful and looks just as nice in person as it is in the pictures. It's up a hill in a lovely neighborhood very close (15 minute walk) to the Vatican. There is a Carrefour express just down the hill and we felt very safe walking around even at night.
I've stayed in many airbnb's in many countries but it's really Andrea and Carlotta's hospitality that makes this apartment special. You really feel that they love meeting people and love the experience of being hosts. I felt like we could have gone to them with anything and it was truly a pleasure being their guests. I would recommend the apartment to absolutely everyone!
