Where better to stay home than a brownstone with its own 33-foot-long pool, a home gym and spa, plus a wine cellar/grotto?

The six-story, six-bedroom, 20-foot-wide townhouse at 45 W. 70th St., near Lincoln Center, features high ceilings, hardwood floors, multiple fireplaces and a $17.5 million price tag (down from its original $19.5 million ask).

There’s also a chef’s kitchen and a rear garden with an outdoor kitchen and fireplace.

The smart-wired home boasts radiant heating and a patio snow-melting system.

An elevator rises to the roof, which is ripe for a deck or penthouse.

We’re thinking sunrise yoga.
