About the property

What makes AC Hotel Sants worth the points.

The hotel sits at Passeig de Sant Antoni 36–40, just 50 metres from Barcelona Sants train station, providing direct connections to high-speed AVE trains, regional services, the airport, and metro lines L1 and L5. This positioning places it in a largely residential area with quick transit to Plaça d’Espanya, the Fira de Barcelona exhibition center, and Camp Nou, while remaining about 3 km from Plaça de Catalunya. The property operates as a smoke-free building with 24-hour front desk service, on-site paid parking, and no pets allowed. Guest rooms feature contemporary minimalist design with air conditioning, Wi-Fi, in-room safes, and satellite TV. The single on-site restaurant, AC Lounge, serves Spanish cuisine for lunch and dinner along with a weekday buffet breakfast available for a surcharge. A bar/lounge is also available, and the hotel maintains a 24-hour fitness center without a pool or full-service spa. Two meeting rooms provide roughly 138 m² of event space suitable for small gatherings of up to 120 people. Complimentary Wi-Fi is offered to Marriott Bonvoy members, supporting the hotel’s focus on efficient urban stays for rail travelers and exhibition attendees.
