If your dream of the perfect Upper Westside Pre-War address involves a prime park block location, a flexible layout, and loveliness all around, then this classically inclined, two bedroom, two bath, high-ceilinged pre-war beauty with modern sensibility will certainly bring a smile to your face. Sweetly situated on one of the Upper Westside's wider, more coveted, quiet, tree-lined Riverside Park blocks, and with big picture windows boasting bright views from both the Living Room and Master Bedroom, this resplendent residence, lovingly built in 1921 by famed architect George Pelham, is a rare Westside trifecta:  a home with a clever Pre-War design, a home in a supreme location, and a home whose floor plan can accommodate all of your growing needs.  The comfortable, bright Living Room has a pleasant vista and room enough for a baby grand piano.  The dining gallery is perfectly situated between the living room and the cook's kitchen - a handsome windowed space offering premium appliances (including washer/dryer!), stone counters, ample cabinets, disposal, and service entrance. The master bedroom has both northern and eastern exposures (cross breezes), accommodates a king-sized bed, and boasts en suite access to its spa bathroom - a classic but stylish windowed retreat with custom cabinetry and a whirlpool soaking tub with heated backrest. The second bedroom is currently configured as an oversized office/den, but is indeed a well-scaled, sunny, south-facing  bedroom in its own right - a feel-good space which is conveniently served by a separate, full, designer guest bath with walk-in rainfall shower with spa bench. If your dream of the perfect home involves a comfortably distinctive, classically-inclined Upper Westside residence situated in a well-served, Pre-War, pet friendly, elevator cooperative with live-in superintendent and bike/laundry/storage rooms - all in a perfectly prime location -   then stop dreaming.  Come spread out in style.
