Frontend engineer for web applications

At Stayforlong, travel is more than a transaction; it's a journey of extraordinary moments. Born in Barcelona in 2015, we set out to disrupt an industry dominated by massive corporations. We believe in the power of prolonged stays — the longer you stay, the deeper the connection, and the better the rate. Travel on your own terms.
