Castilla Termal Burgo de Osma  

In the heart of El Burgo de Osma’s historic centre, a 4-star spa hotel occupies a Renaissance building that once served as a university. You’re steps from Plaza Mayor and a short walk to El Burgo de Osma Cathedral, with Santo Domingo de Silos Monastery and regional Romanesque sites close by.

Seventy individually decorated rooms and suites blend period architecture with modern comforts. Rooms feature minibars, premium bedding, bathrobes and private bathrooms with rainfall showers. The property keeps its historic character while delivering a calm, contemporary spa vibe.

Relax in a thermal spa fed by mineral‑medicinal waters, and enjoy indoor and seasonal outdoor pools (the thermal pool runs scheduled sessions with dedicated children time). Facilities include a sauna, steam bath, massage rooms, fitness centre, library, 24-hour reception, concierge and on-site parking.

A business centre and dedicated conference, meeting and presentation facilities make the hotel suitable for events and small corporate groups. Complimentary Wi-Fi keeps you connected; airport shuttle and parking are available for a surcharge.

Argaela restaurant highlights local, seasonal produce and regional flavours. There’s also a coffee shop/café and a bar/lounge for evening drinks. Buffet breakfast is served daily (for a fee) and limited room service is available.
