Who's Afraid of Dracula?

Why would a castle in Transylvania have the five bathrooms Giandomenico Fracchia (Paolo Villaggio) needs, and why is its owner, Count Vlad (Edmund Purdom), so eager to receive him? Fracchia has three days to sell a house with at least five bathrooms, and his friend Rag. Filini (Gigi Reder) has found the place. Neri Parenti sends the pair into the count's home, where Vlad's sister takes a liking to Fracchia, and his job hangs on the sale.
