I stayed at 'Home in Rome' for one month while I was working at one of the universities. Ilaria was a wonderful host: very welcoming and helpful and really made me feel at home.
The apartment is very spacious and comfortable and only 15 minutes journey from central Rome (five minutes walk to the Metro). It is in an interesting location with shops and other amenities including some great trattorias nearby.
Garbatella, where the apartment is located, is an interesting area - very authentic with some incredible architecture. I would definitely recommend staying here.
