If this elegant 2-bedroom looks like a soaring example of NYC’s rich architectural history, that’s because it is: The mint condition home in the Adlon has been renovated in keeping with its past. The original honeycomb ceiling and oak floors are complemented by skim-coated walls, new windows, a renovated kitchen with dishwasher, and a new bath. Monthlies in this full-service co-op are just under $2K. Jude Dayani at Brown Harris Stevens is the listing agent.

This studio has been smartly transformed into an efficient and inviting home, thanks to an open kitchen with recycled-glass counters and a Murphy bed with attached wardrobe made of solid walnut. Its Horatio Street location — in a pet-friendly co-op with an elevator and generous purchase and pied-à-terre policies — makes this a winner from Barbara Blumberg at Millstein Group.

More than 300 potential buyers have earmarked this bright and blond-floored 2-bedroom as a favorite, thanks to its prewar detail, updated bathroom, and new, windowed kitchen with dishwasher. Monthlies are under $800 in a financially sound co-op in Prospect Heights, where other units have historically sold for over list price. Lesley Semmelhack at Corcoran Group is the seller’s agent.

With its glass-paneled pocket doors and built-in bookcases, the interior charms of this Upper West Side 1-bedroom would be enough to seal the deal, but look what else it’s got: a private terrace! Plus it’s set in a brownstone just one block from Central Park and conveniently close to the 1, B, and C subways at West 86th Street. Jane Calvin at Compass is the listing agent.

Finally, if you’re looking at NYC open houses on February 8 and 9, look no further than this light-filled townhouse for magazine-spread perfection. Decked in original wood trim and configured as a two-family, the owner’s unit is a majestic triplex with 4 bedrooms and 4.5 bathrooms, with a wood-burning fireplace and an eat-in chef’s kitchen. A garden-level apartment is a cash-creating rental that backs onto a private yard. Tali Berzak at Compass represents the sellers.
