Duve Powers 30% Increase in Guest App Engagement at SLS Barcelona During Primavera Festival

MARKETING

SLS Barcelona, a luxury 471-room hotel under Ennismore's portfolio, opened its doors in early 2025. The hotel delivers a 5-star guest experience focused on premium hospitality, lively experiences, and culinary excellence.

Why it matters: SLS Barcelona partnered with Duve to replace front desk queries with proactive, multilingual communication sent directly to guests’ phones.

From dining options to event schedules, guests now receive timely updates via the Guest App, WhatsApp, and email - all tailored to their language and interests.

Top 3 Core Objectives: SLS Barcelona faced challenges in engaging a global audience during major events, promoting its on-site venues effectively, and maintaining seamless, real-time communication with guests to ensure a consistent, high-quality experience.

Engaging a Global Audience: During local events like the Primavera Sound festival, SLS Barcelona welcomed guests from around the world. Creating consistent, multilingual communications and promoting hotel programs across multiple channels was time-consuming and difficult to scale.
Informing Guests About Events: With six F&B venues including two restaurants, a rooftop bar, and poolside programming, SLS Barcelona needed a streamlined way to inform guests and drive interest, without relying solely on staff to manually promote offerings.
Providing Seamless, Real-Time Communication: Guests needed a fast and convenient way to reach hotel staff, and timely responses were essential. Ensuring smooth, efficient communication was critical to maintaining a high-quality guest experience.
