Dario was a fantastic host, checking us in late in the evening and showing us all the features of the studio (which consists of a large bedroom-kitchenette and bathroom separated by a door from the bigger apartment). The studio is located in the student area of the city so it is great for cheap-eats and local shops for making packet lunches (Rome is quite expensive, especially if you're having lunch in the tourist areas).
The studio is very comfy and clean and everything you need for a great holiday in Rome. Dario was contactable throughout the holiday. He even booked us a taxi from the apartment to the airport.
