Hi Clare,
this is Margherita from m-cube production Company in Rome. Could you tell me when you are planning to shoot? Our staff is quite busy with tv documentaries and commercial shootings until end of September, but if you like I can introduce you some free lancer production assistant in Rome.
anyway, i suggest you to have a look to Villa Parisi, it is a bit outside of Rome center, but it is really a tipical reinassance period Palazzo, with amazing inside rooms and also beautiful italian style garden. it is almost empty, but with a lot of frescos.
regards
Margherita
