“What makes it so spectacular is the location — on a valley surrounded by beautiful mountains, but close to natural sandy beaches,” Mr. Feliu wrote in an email.

A long gravel driveway leads to the property, which is anchored by the 3,700-square-foot villa. The front door opens to a foyer. To the left, in what was once a kitchen, is a den with a brick fireplace. To the right is a library with built-in bookshelves and a stone fireplace.

Straight ahead from the foyer is a long common living area, with wide floor beams and high ceilings. At one end is an open office on an elevated platform. A dining table and a seating area with a fireplace are in the center. A second seating area with aluminum-framed French doors opening to a patio is at the opposite end.

Past the library is the kitchen, with a wood dining table, a marble-topped island with built-in appliances, and doors leading out to the grounds. (The antique, designer and custom furnishings are available to buy, but not included in the asking price, Mr. Feliu said.)
