For two couples travelling together this was perfect. In effect, two one bedroom flats but in a shared unit, you could be all together when you wanted but have your own private space as well.
For the Vatican it couldn't have been better - just one street over - and yet the centre of Rome was only a few stops on the Metro.
And within the city walls so fixed taxi rate of 30eur from and to Campiano airport - although I had to be insistent with the driver that it was!
