Meet your new UWS neighbor: Ekaterina Rybolovleva. She’s your normal, run-of-the-mill, 22-year-old daughter of a Russian billionaire, and she just bought an $88 million dollar apartment on the Upper West Side.

This week’s “unattainable” apartment is a brownstone located at 12 West 83rd. Newly renovated and located just steps from Central Park on a tree-lined street, it features 5 BR, 4.5 BA, a terrace, private backyard, and massive storage space.

This week’s “unattainable” apartment is #8G at the Beresford, located at 211 Central Park West (between 81st & 82nd). Facing Central Park and just steps away from the American Museum of Natural History, this elegant  9-room, 4-bedroom, 4-bathroom apartment has park views from the living room, library, and master bedroom.

This week’s “Unattainable Apartment” is a rarely available Renaissance Revival style mansion designed by Edward Angell and built by William Noble in 1888. Sitting at 249 Central Park West (corner of 85th), it features expansive park views from every room.

This week’s “Unattainable” Apartment is #48DE at The Millennium (101 W. 67th). Compared to the $88 million penthouse at 15 CPW mentioned earlier in the week, you could pick up EIGHT of these babies and still have $40K leftover.
