An "abundance of space" is not the description you might ever expect for an alcove studio on the one of the Upper East Side's most charming tree-lined blocks, but you'll change your mind once you tour this Convertible 1 bedroom apartment one of the Upper East Side's most desirable tree-lined streets. Everything about this apartment is spacious, from the 28-foot living room, to the dining area that accommodates an 6-person dining set, to the bedroom area which can easily accommodate a king-size bed, to the separate dressing room which can become the ultimate walk-in closet. The nearly 700 sq. ft. is larger than many "true" 1 bedrooms making it easy to convert this (with 2 different conversion options). The orientation towards the back gardens is exceptionally quiet, yet still offers open and delightful views of gardens and treetop greenery. And since you can never have enough space: a large private in-building storage unit is available with this sale for an additional $2100 and a monthly fee under $40 / month (billed annually). The Mayfair is a highly sought-after, pet-friendly, full-service co-op with 24 hour doorman, live-in super, and responsive staff. The building features a private garage, bike room and card-key laundry room on each floor. The 6 and G subway are around the corner as are JG Melon, Maison Keyser, Payard, Arlington club, Mezzaluna, Equinox Fitness Club and just 4 blocks to Central Park. Come see the versatility of this extra large apartment and experience why the Mayfair and this charming block are so beloved. Some photos are virtually staged.
