On a quiet, tree-lined stretch of Ocean Parkway near Avenue L, apartment 6L is an unusually large studio — 642 square feet on the sixth floor of a well-kept 1940 elevator co-op — freshly renovated and ready to move in. As a top-floor corner unit it has no neighbors on either side — one wall is the building's exterior, the other the elevator — and no one overhead, six floors up among the treetops of Ocean Parkway. The hardwood floors have been refinished, the walls freshly painted throughout, and the bath re-glazed. The work is done — what's left is to move in. The main living room runs nearly 21 feet with light from three windows, leaving room for a full living area and a separate sleeping area without either feeling crowded. A large foyer works as a dining room, home office, or room for a wall-to-wall closet of your own — a second space most studios don't offer — and the kitchen's breakfast nook has two windows for bright morning meals. The windowed full bath sits down a short hall, and storage runs well beyond the studio norm — two closets in the foyer and two more along the hall. Ceilings are high, the rooms stay bright, and the apartment has the solid, settled feel of prewar Ocean Parkway construction. Maintenance is $571 a month and includes heat and hot water — a low carrying cost, and a notably low one for this building. Residents share an elevator, a live-in superintendent, a card-operated laundry room, a bike room, private storage, a voice intercom, and a handicap-accessible lobby. Subletting is permitted with board approval after two years of ownership. Ocean Parkway's landscaped walking and cycling paths are at the door; the Q at Avenue M, local and express buses, and the shops and restaurants of Avenue M and Kings Highway are all close, with street parking nearby, while the block itself stays quiet. Walk Score 82. Shown by private, pre-qualified appointment, at the owner's request.
