Omni La Mansión del Rio in San Antonio: A River Walk Story Since 1852

A Hacienda Vibe on the River Walk

Omni La Mansión del Rio plants you right on the banks of the San Antonio River Walk, where the property'sSpanish colonialarchitecture and European-style limestone walls give the place the feel of a grand hacienda. The address, 112 College Street, San Antonio, Texas 78205, sits inside a downtown riverside district that blends natural waterway scenery with surrounding dining, shopping and entertainment options. From this base, nearby landmarks such as the Alamo, Historic Market Square and Riverboat Tour departures are all within easy reach of the hotel's College Street front door.

Roots in a 19th-Century Schoolhouse

The building that now houses Omni La Mansión del Rio has a backstory tied to early San Antonio education. In 1852, sixteen years after the fall of the Alamo, four brothers of the Society of Mary arrived in the city to establish a school. Construction began immediately, and the doors opened on March 1, 1853, welcoming more than a hundred students. By fall 1854, two additional brothers had joined the faculty, and by 1870 the campus had grown into a well-proportioned limestone structure described as typically European in style. The College Street campus continued to flourish first as St. Mary's Academy until 1924 and then as St. Mary's College, leaving the present-day hotel with a layered academic heritage that the property highlights as part of its identity.

Rooms and a Recent Refresh

The hotel carries 338 guest rooms and suites, each designed to celebrate the romance and history of the River Walk in downtown San Antonio. The property completed a multi-million-dollar renovation in the spring of 2020, reinforcing its role as a longtime fixture of the city's hotel scene. Interiors pair Old World design touches with contemporary finishes, and room configurations span options suited to solo travelers and families alike.

Facilities for Lounging and Gatherings

A year-round courtyard pool anchors the outdoor leisure offering, while spa services at Mokara Spa provide a soothing counterpoint. The property also dedicates more than 18,000 square feet of event space to meetings, gatherings and special occasions, giving groups ample room alongside the leisure amenities. Hotel policy notes that guests must be at least 21 years of age to check in and must present a valid photo ID, and the property enforces a strict no-party policy in guest rooms. Maximum occupancy stands at three for a room with a king bed and four for a room with two double beds.

Long-Standing Diamond Recognition

The hotel is described as a Four Diamond property that meets high standards of service, amenities and overall quality, with the rating reflecting a refined, upscale experience.

Travelers coming from the north via Highway 281 or IH-35, or from the east via IH-10, can follow the listed routing toward Navarro Street and the downtown grid that leads to the hotel.

Practical Considerations
