The entrance hall floor is laid in a geometric design with Siena yellow, red, green and oyster coloured marble. The portrait of Her Majesty the Queen is by Luciano Guarnieri and is the first authorised copy of the original by Pietro Annigoni. The banister in brass effect to the main staircase and the sea green carpet harmonise with the marble of the hall columns and the skirtings on the stairs. The Queen for President Ciampi took place in the ballroom which overlooks the garden. The doors and windows are all dressed with romanesque arched architraves and embrasures in yellow Siena marble.
Piranesi prints hang between each window.
The ballroom has recently been air-conditioned to allow it to be used for conferences, concerts and trade promotions throughout the year. The inter-connecting rooms of different sizes provide flexible entertaining space for the Villa's many guests. The main feature of these rooms is the series of four Mortlake tapestries based on cartoons by Raphael. The tapestries are on loan from the Duke of Buccleuch. The Salon Rose is particularly suited to small scale lunches and dinners The Grande Salotto can accommodate large receptions.
