We stayed at Antonio and Valentina's for 4 days. The communication before the trip was perfect. Not only Valentina sent us a lot of information about restaurants in the area, but she also booked our driver who was waiting for us at the airport. Antonio made sure to welcome us in although it was late in the night. There were simply no issues throughout our stay and each time we had a question, Valentina replied within 5 minutes via whatsapp. The apartment is in a great, lively (and sometimes noisy) location and we walked everywhere - 20 minutes to the Vatican, 5 minutes to Trastevere, 15 minutes to the Colosseum. Just perfect!
