We spent 3 days at Enrico's flat and had an amazing time there. The place was exactly as you see it in the pictures, clean, comfy and spacy. Enrico was very helpful and kind getting us set there and helping us with some tips. He showed us the local supermarket which is a block away, and the stops where to take the buses to go to the metro that will take you to the main points (in Anagnina - 6 mins). Also Enrico arranged our taxi from and to the airport for an affordable price, and also was kind to give us a bottle of fresh homemade wine as a gift. Nothing bad to say about the place or Enrico, it was a wonderful experience.
Tip: if this is your first time going to Rome, know that buses and metros are the best way to go around the city BUT remember that you must buy your tickets before getting into any bus. They won't allow money (1.50 eu per ticket/ same ticket works for 100 minutes and you can take any amount of buses during that period, plus one trip in the metro).
Tickets can be bought few blocks away from the apartment, just ask Enrico and he will show you.
