Description

With 8 windows and 58 linear feet overlooking Park Avenue and its beautiful planted islands, 7AB at 525 Park Avenue is without question one of the great rental opportunities in the luxury category. Generously proportioned public rooms plus an exceptionally bright, well-appointed eat in kitchen, combined with large and very light bedrooms with limestone clad en-suite baths and walk-in closets create a zoned living space, which flows seamlessly. High-end finishes, floor-to-ceiling doors, beautiful hardwood floors and moldings throughout punctuate the space. The additional fully equipped kitchen, on the east side of the apartment, creates the opportunity for a second dining area for children, staff, and general convenience. This 3620 square foot apartment affords more than ample space for a gym, a home office, and off-season clothing storage. The layout of the apartment also affords a wonderful space for gracious entertaining, either formally or informally, and the large dining room, which adjoins the light-flooded kitchen, makes entertaining easy with or without staff. The grand dining room connects to the huge corner living room via a beautiful archway, facing Park Avenue. Additionally, there is a huge family room / library which functions perfectly for informal living. This apartment lives as though it were a house. There is a very good area for the principle bedroom and three others, all of which have great privacy. The 10 closets within the apartment offer a more than ample storage space, a rarity not normally found in pre-war buildings. A white glove lobby staff ensure maximum security for any resident of this rare pre-war condominium on Park Avenue. The location of this rental opportunity is second-to-none in the world in terms of proximity to high-end shopping, cultural institutions, and fine dining. A few minutes away, one will find the world's finest luxury shops and within 2 blocks one may enter Central Park, the very heart of Upper Manhattan. With the subway only two blocks away and the Lexington Avenue and Madison Avenue bus lines available one block from the building's front door, public transportation abounds. 525 Park Avenue is an Italian-Renaissance-palazzo style 14-story prewar building built in 1914, and converted to a condominium in 1989. Schwartz & Gross designed this building and many other apartment houses on Park Avenue including 470, 885, 888, 910, 911, 930, 941, 970, 983, 1045, 1070, 1125 and 1165.
