Description
Possibly the most gracious, well-located studio on the Upper West Side! Apartment 5A is a flexibly configured studio/one bedroom apartment in The Galaxy with approximately 512 square feet of old-world charm and all the modern conveniences. The Galaxy, an elegant 14-story co-op at 81st Street and Columbus Avenue, overlooks the Hayden Planetarium and the Museum of Natural History with its beautiful grassy park and weekly farmers’ markets. Currently used as an extremely spacious studio with windows facing west onto Columbus Avenue, Apartment 5A would convert very easily to a comfortable one-bedroom apartment (See Alternate Floor Plan). This studio has many features more commonly found in larger apartments: 9 ¾’ ceilings; tall windows; a separate windowed kitchen large enough to comfortably accommodate a proper dining table and chairs; and a gracious entry hallway leading from the front door to the living space with a spacious hall closet and a large windowed bath on either side of the hallway. The living space benefits from hardwood floors and an easy-to-operate and very comfortable Murphy bed which would transfer with the apartment. Residents of The (pet-friendly) Galaxy benefit from a full-time doorman as well as a live-in resident manager. The beautiful, planted roof deck with its panoramic views is available to residents for private use or entertaining. Other important tenant amenities include laundry facilities on every floor, bike storage and a package room. The Galaxy is currently in the process of replacing the carpeting and wallpaper in the upstairs hallways and refurbishing laundry and compactor rooms. These improvements have been fully financed through a recently collected assessment. The Galaxy was built in 1905 with lovely pre-war detail including intricate window cornices and scroll work and a beautiful mosaic floor in the lobby. The 81st Street Park block is arguably one of the prettiest and "handiest" on the Upper West Side. Less than a block to Central Park, it is convenient to world-class specialty stores such as Zabar's; fine restaurants, boutiques and has ready access to multiple subway lines and the 79th Street cross-town bus. Apartment 5A at The Galaxy is in the beating heart of New York's art and cultural center with the opera, dance, symphonic music, jazz and film offerings of Lincoln Center in walking distance. Ownership at The Galaxy is very flexible with pieds-à-terre, co-purchases, gifting and guaranteeing allowed on a case by case basis. Further, financing up to 75% is permitted as is sub-letting after one year of ownership with Board approval. There is a flip tax of $12/share payable to the corporation, $3,996 in the case of Apartment 5A (333 shares).
