If you are a serious home entertainer, cringe at the sight of unused space, or just love to sit, the totally over-the-top built-in seating at this $5.8 million Flatiron condo could hit the spot.

Just look at the picture above -- a nearly 40 foot wall spans the length of the space, with dimpled leather window seating running all alongside (click on the other pictures within the StreetEasy link to see just how much seating there is!).

In some ways it feels more like a nightclub than apartment, but wow, talk about a great party spot!
