Yoga Spa Lounge 1881 – Yoga Spa Lounge 1881 review. On a whirlwind stop through the Upper East Side. Sassy discovered a true hidden gem in Yoga Spa Lounge 1881. It is a refreshingly unpretentious studio that stands out from Manhattan’s typical fitness scene. No flashy branding or influencer energy here, just a grounded, welcoming space that feels like a deep exhale amid the city’s chaos. The room is spacious, dark, and airy—an instant sanctuary—and the Hatha-style flow was slow, steady, and blissfully non-competitive. It’s rare for Sassy to fully unwind, but this class delivered the kind of gentle reset that melts tension, soothes sore muscles, and quiets a busy mind.
