Everything about this 4BR/4BA loft at 43 West 64th Street?which just hit the market for $8 million?screams extravagance: shiny black hardwood floors, glittering chandeliers, barrel vaulted ceilings, plump leather couches, metallic accents, and not one, not two, but three baby grand pianos. And it's no surprise why. The Observer reports that the seller is Russian princess Kristina Kovalenko, whose favorite drink is $5,000-a-bottle cognac. Kovalenko bought the 3,667-square-foot place for $4.2 million back in 2009, and the listing broker said that the nearly 100 percent price increase is "reflective of all that has changed since the depths of the recession." Hmm, do you agree?
