Job Description

We are Stayforlong, and for us travel is not just a means to an end but a journey of extraordinary moments and remarkable discoveries.

As firm believers in the enriching power of prolonged stays, we are passionate about nurturing meaningful connections with the places our customers visit. We reward their commitment to the journey with progressively cheaper rates, encouraging them to immerse themselves in the very essence of each destination.

We were born in Barcelona out of the need to disrupt an industry dominated by big corporations dictating how we should travel.

Since 2015, our commitment has been to empower our customers to break free from the constraints of an oversaturated market. We strive to offer a fresh perspective, giving them, hoteliers and our partners, the flexibility, opportunities and choices they deserve.

About the team

At Stayforlong we are currently a team of 80 people working in a dynamic and collaborative environment where people have the opportunity to grow and develop professionally.

We strongly believe in equal opportunities for everyone, both in the workplace and beyond. We like to create spaces where everyone's ideas are equally valued and heard.

We started in a difficult business environment and have grown from there, which is why we admire nonconformists who fight against the odds, refuse to be intimidated, and help others along the way. With our digital DNA, we thrive on challenges, love to think outside the box, and move with the times.
