Known as one of the most affluent neighborhoods in the cities, the Upper East Side boasts high-rises and tenements, which abound in 20^th Century neoclassical style mixed in with some post-war luxury high-rises. Notably, this area, though historically one of the most expensive blocks in Manhattan, is now becoming an affordable hub, especially for two and three-bedroom properties. There are some amazing units in this swath of uptown Manhattan, where you can enjoy affordable housing surrounded by elegant dining, shopping and museums.
