The $18 million Tuscan-style California estate includes a $100,000 Italianate estate.

This Calabasas home comes with a temperature-controlled wine cellar, saltwater aquarium and... with a luxury vacation in Italy?

Yeah, you read that right. If the seller of this $18 million villa accepts the full-price offer made through escrow, they will add a $100,000 trip to Portofino and Lake Como.

Well, this is really a first. Not to belabor the point - though we're not sure which part of this deal is more exciting - this majestic villa spans an impressive 13,000 square feet and sits on a nearly 1.5-acre lot in the Estates of the Oaks conservation villa community.

Imagine Versailles limestone floors, ceilings of century-old, treated wood beams and European terraces. Inside, there are six dreamy bedrooms and ten bathrooms, including two master bathrooms with views of the Santa Monica Mountains.

The apartment, inaccessible to the paparazzi, features a number of luxurious amenities expected of an estate of this caliber, as well as some unusual additions. Among the accustomed accompaniments are a 15-person movie theater with its own concession counter, a resort pool and an 800-bottle temperature-controlled cellar.

On the other hand, aquarium lovers will be delighted with the 500-gallon saltwater aquarium and Koi pond with waterfall.
