I don't offer only flats, but also study trips to the surroundings. You can hire a car with driver and guide for the whole day and visit places out of Rome. Some example for destinations:

Albanian Hills (Castel Gandolfo, Nemi, Ariccia...)

Palestrina - Preneste

Cerveteri - Etruscian tombs

Roman Villas in the outskirts of Rome

Tivoli - Hadrian's Villa

Sermoneta - Ninfa

Please ask me for more information
