1624 20th Street in Potrero Hill just came onto the market asking $2,495,000. The 2-bed, 3-bath home is rumored to be owned by the same couple who just picked up Twitter co-founder Evan William's house in Noe Valley, which would explain why their current digs are on the market now. In addition to all the fancy finishes and designer plumbing fixtures that are used throughout the space, the home has some very unique qualities. There's a fabulous dressing area in the master suite, and a bedroom that looks like a two-bed train car, because apparently one of the past owners had twins who loved trains. Other quirky highlights include a secret passageway for a panic room and a zen garden out back.
