Casa Osito | Pool, Hot Tub & Outdoor Dining Minutes from Sonoma Plaza

Welcome to Casa Osito by AvantStay!

Tucked beneath a canopy of heritage oaks in the heart of Sonoma wine country, Casa Osito is your private, poolside sanctuary designed for laid-back luxury. Whether you're lounging with a chilled glass of rosé beside the sparkling pool or unwinding in the hot tub beneath the stars, this home blends wine country charm with contemporary comfort for unforgettable gatherings.

Step inside to discover a bright and open interior that flows effortlessly from the gourmet kitchen to the cozy living room. The chef’s kitchen is outfitted with stainless-steel appliances, a spacious island, and generous counter space for prepping family-style meals. With seating for 8 at the dining table and 3 more at the breakfast bar, there’s room for everyone to gather.

When work calls, a dedicated office offers quiet focus away from the fun. And when it’s time to play, your private backyard delivers—complete with a shimmering pool, hot tub, lounge chairs, a BBQ grill, and an alfresco dining table for 8.

Casa Osito comfortably sleeps 8 across 3 inviting bedrooms and a bonus room. The primary suite features a king bed and luxe ensuite with a walk-in shower and dual vanity. A queen room and a twin-over-double room offer flexible sleeping options, while a sleeper sofa in the bonus room is perfect for an extra guest.

Located just minutes from Sonoma Plaza, your group can easily explore tasting rooms, boutique shops, world-class restaurants, and nearby wineries. Spend the day hiking in Sugarloaf Ridge State Park, picnicking at Bartholomew Park, or catching golden hour views over the valley—then come home to your own private retreat.

AvantStay provides an upscale experience with services that elevate your stay and save time so you can enjoy every moment. Guests have access to a 24/7 support team and a tech-enabled concierge to book services, such as fridge stocking, mid-stay cleanings, and private chefs. For anything you need (or never knew you needed), we’re at your service!

Known for its vineyards, local cuisine, and nature parks, Sonoma County (45 minutes from San Francisco) offers a wide array of activities for those looking to retreat from city life. Touring local wineries, dining at farm-to-table restaurants, and visiting world-class spas are classic ways to experience the area. While unwinding is certainly the attitude in Sonoma, activities like horseback riding, hot-air ballooning, and kayaking attract those looking for a little adventure. In the evening, watch the sunset over the vineyards and rolling hills, wine glass in hand.
