I run a tech company and live at the top of a classic Upper West Side brownstone, a duplex just a few steps away from the American Museum of Natural History and a block from Central Park. You'll have the master bedroom on the top floor: a private bedroom and bathroom as well as use of the living room, laundry, kitchen and 2 private terraces. It's a quick walk to the 1, B and C trains that will get you anywhere in the city, and if you've got a car street parking is available right on the block.
