Our week at Mauro's place was a great experience. The apartment is 40 minutes long from the airport (direct train for 8 euros) and around 20 minutes walk from Colloseum. The neighbourhood is not that central but we loved it even more as there's some local charm and non-touristic atmosphere. In walk distance you will find several supermarkets, cafes and restaurants; Pompi cafe is around 7 minutes walk and that's the greatest tiramisu place in the whole world. The only thing that you might need is a pair of earplugs (the street is a bit noisy).
Mauro is very warm and nice person. He's friendly, tactful and was always open for some advice and recommendations. Mauro's cat is now a good friend of ours and spending some time with the her on the flat's terrace every morning made our stay really great. We definitely recommend this place for a person or a couple.
