I stayed at David's with my son for a week in March 2017. I can recommend his apartment for sure: it's spacious, well equipped and comfortable to live in. There are several supermarkets and nice cafes nearby. The apartment is quite close from the center of the city (it takes 30 minutes to walk to the Colosseo). David was very helpful and kind to give us some advice on where to find good Italian pizza (it was really delicious and the price was good).
