Dario was a great host. Even though he couldn't be there to welcome us personally he had his mother meet us at the flat and check us in. She was even waiting with some sparkling wine for us as we were celebrating our birthdays. Dario was very contactable through Whatsapp (replied within 10 minutes) and gave us great recommendations for places to eat in the neighbourhood. He even sent us menu suggestions and the directions. No surprises with the apartment - it had exactly what we needed for 4 night stay. Very comfortable and clean with good facilities. The only caveat I would have in recommending the apartment is that it is a bit far from the city center - it takes minimum 30 minutes to get in. But there are good bus links (including night buses) and you can even walk to the Tiburtina station if you are so inclined. We just bought a 72hr transit pass and were set. And the quality of the apartment and Dario as a host definitely make up for the distance. Dario was an outstanding host and I would definitely recommend the apartment.
