I live on Manhattan's Riverside Drive, near Columbia University. My lovely 1907 apartment overlooks Riverside Park and the Hudson. Fully renovated, it has 2 bedrooms, one with a king and one with a queen bed, one large and one small bath (one tub/shower, one shower), great kitchen with all mod cons and good cookware, laundry room/office, music room with small grand piano, living room and dining room with expandable table. It's gorgeous (she said modestly) , comfy, quiet, and in a wonderfully friendly building and neighborhood.
The area is very lively--lots of Columbia students and faculty, extremely international. Transportation is very convenient--one block to several buses, three blocks to the subway. Everything you could need is available nearby, and access to the rest of the city is quick and easy.
One caveat--my downstairs neighbor is very sensitive to noise, so we request that guests wear only socks or slippers in the house and tiptoe or levitate early in the morning or late at night.
Due to new building rules, the apartment is no longer available for stays of less than a month. This is regrettable, but I'm obliged to comply.
Due to a six-month sabbatical, my apartment is available in 2018 from early February until mid-September. I would love to rent to one couple or small family for the entire time, and will significantly reduce the rent for such a person.
