Roberto is a great host. He gave us some useful tips on how to get to his place and welcomed us with a bottle of wine, pie, ice tea, soda and sweets for the kids. Five star!
The apartment is brand new and is by far the cleanest place we've been at. It has anything you'd need - from iron and hairdryer, to salt and sugar. In fact, we felt very much like at home. It was perfect for the kids too.
It's very well located - 2 minutes from the metro station and 5 minutes from the Vatican.
When I come back to Rome, I'll definately stay at Roberto's place again.
I highly recommend it to anyone.
