According to Pliny the Elder, there were two kinds of villas: the villa urbana, which was a country seat that could easily be reached from Rome (or another city) for a night or two, and the Villa rustica, the farm-house estate permanently occupied by the servants who generally had charge of the estate. The villa rustica centered on the villa itself, perhaps only seasonally occupied. Under the Empire there was a concentration of Imperial villas near the Bay of Naples, especially on the Isle of Capri, at Monte Circeo on the coast and at Antium (Anzio). Wealthy Romans escaped the summer heat in the hills round Rome, especially around Frascati (cf.Hadrian's Villa). Cicero is said to have possessed no fewer than seven villas, the oldest of which was near Arpinum, which he inherited. Pliny the Younger had three or four, of which the example near Laurentium is the best known from his descriptions.
