Location, Layout, and Views define this exceptional full-floor Lenox Hill condominium, available for the first time in 25 years. With 360 degrees of wide-open views, a private 25' elevator landing, and rare fully-circulating floorplan, the Siena's 29th floor is like a private castle set above Lenox Hill. The large entry gallery leads to a dramatic entertaining space where south, west, and north exposures take in all of Central Park and the city beyond. The expansive 28-foot living room is framed by a sunny southwest corner dining room, and comfortable library/media room to the north. At the center of the tower's south exposure is its large eat-in kitchen, conveniently accessible from the entrance foyer, dining room, or from the home’s private wing of five bedrooms. The playfully colorful kitchen features painted herringbone floors inlayed with geometric designs, cerulean blue cabinets, and a center island with breakfast bar. A built-in breakfast table enjoys a dramatic southwest view toward Central Park South. The enormous primary bedroom suite faces east and south, and includes two walk in closets, and a raised sitting space. The primary bath features dual sinks, large shower, and a tiled soaking tub with open skyline views. The second bedroom suite takes up the tower’s northeast corner, and is currently used as an artist's studio. The third and fourth bedrooms face north, sharing a windowed bathroom in between. The bright south and east facing fifth bedroom with ensuite bath is located right off of the kitchen, perfect for guests or caregivers. Originally purchased directly from the building developer, the sole owner has customized the entire floor to enhance light and space. With ceiling heights over 9’, a vibrant palette of bold hues and warm metallics flows through the home; across Venetian plaster, painted hardwood, brilliant tiles, inlaid swirls of carpet, and colorful sunshades. Being both a one-of-a-kind artwork and a intelligently designed residence, the 29th floor is ready to comfortably accommodate any household. The Siena is an impeccably maintained full service Upper East Side condominium, one of only a handful of Lenox Hill residential towers built west of 3rd Avenue. There is a full-time 24 hour doorman and concierge, large fitness center with sauna, a common terrace and a playroom.
