100 W 12Th St

The Mark Twain is a six-story cooperative building completed in 1959 and located at 100 West 12th Street in Greenwich Village. The mid‑century structure houses primarily one- and two-bedroom units along with a range of alcove studios; many apartments feature high ceilings, abundant closet space including walk‑ins, and windowed kitchens and baths. Interiors often include details such as granite counters, built‑in shelving, dining alcoves, and soaking tubs; select residences have been combined to create larger floorplans and private terraces. Common areas and services reflect an established, well-managed coop: a part‑time doorman, a live‑in superintendent, full‑time maintenance staff, a renovated lobby and hallways, central laundry, bike storage, and private storage (by waitlist). The building also maintains an in‑building garage with preference for tenant‑shareholders. Pet ownership is permitted and the co‑op allows co‑purchasing, gifting and subletting under board rules, though pied‑a‑terres are not allowed. Situated at the crossroads of Greenwich and West Village with easy access to multiple subway lines, nearby markets and restaurants, the building combines traditional cooperative governance with a village-scale urban lifestyle.
