What does the most expensive house in one of America's most expensive cities look like? According to Curbed SF, 2250 Vallejo St., a circa 1901 mansion turned contemporary dream home built on one of San Francisco's highest streets, just became the most expensive listing in the city.

Meticulously refurbished on the outside and completely recreated on the inside, the 9,095-square-foot home is a rare mix of modern luxury and historical character. It has seven bedrooms and seven bathrooms spread out over three floors. Neal Ward Properties has the listing.
