Excellent place. Marco is great host, helpful and friendly. The room is cozy, comfortable and clean. The kitchen has everything you need.
Location is also fine - 30 minutes from the airport, Metro B Piramide station in 10 minutes of walk, bus 23 stops in front of the door and will transfer you to Vatican museums in 30 minutes. Testaccio Market in 15 minutes of walk, 24/7 Carrefour in 5 minutes.
Good WiFi speed, experienced no problems with the Internet connection.
I would recommend this place.
