The flat is exactly what you see in the pictures. Emanuele is very quick in what concerns answering any question. The location, although it seems very far from the centre, is EXCELLENT. In less than 15 minutes you'll be in the centre of Rome (a 10 minutes ride by tram + the underground). The neighborhood is very safe and you can find anything you need (small groceries with fruit, water, basic things you may need; a bakery, with warm bread and very tasty cakes, a few places with food "to go", and even very good ice-cream just around the corner. I don't advise you to go to Carrefour, as this is much more expensive than the other one Emanuele recommended.
This was our first experience with airbnb, and I am completely into it.
Thanks Emanuele, and your brother too.
