We stayed for a week - during Christmas - in Francesco's appartment (2 parents and 2 teenage daughters). The appartment was very spacious and a good place to relax after walking in the city. It is located in a very nice neighbourhood with plenty of good restaurants and nice shops. You can reach either the Colosseum or the Vatican by walking 25-30 minutes. It is perfectly located in the middle. We really enjoyed our stay here and everything went very smoothly.
