Thanks to Valentina, we've got great days at Rome. First of all she helped us with transfer from airport and back to airport. And she was always in contact and answered even at night when we leaved.
The flat was fantastic: street was quite at night (quite for Rome, because of course sometimes people talk loudly and ambulance car and garbage truck drive through street), and you need to spend only 3 min to be at the entrance of vatican museum (wich is really cool, because, if you book vatican gardens ticket, excursions starts early morning).
Two steps to Carrefour and good restaurant with good promotion menu.
Highly recommend for tourist.
