About

Designed with young travelers in mind, Onefam is where you’ll meet amazing people, uncover Barcelona’s hidden gems, and have the time of your life. We mostly recommend it for travelers aged 18 to 45.

What really makes our hostel unique and what has helped us win HostelWorld awards year after year, are our amazing team and incredibly social atmosphere.
Our staff are travelers just like you, but we are not just here to party. We will cook you dinner, take you on daytime adventures, and share our expert knowledge of the city.

If you still need more convincing, Onefam Sants is an easy 12-minute walk from Sants Station, the main train station in Barcelona. We are also very close to Camp Nou (Barcelonas football stadium), and near Montjuic (Barcelona's largest mountainous park).


- Why us?
Social but responsible.
Day and night, we do free activities with our Onefam guests, including weekly family dinners. At Onefam you arrive as a solo traveler and you leave with a family.

The staff were very welcoming and friendly for the entirety of my stay. The receptionist was constantly reaching out on the group chat about activities and rules during your stay. Overall great experience, would definitely consider booking another night with them.

Hostelworld says

We like that Onefam Sants is only a 30-minute walk from the Sonar festival, and is also very near Badal metro station on Line 5 going to Passeig de Gracia and La Sagrada Familia. Many Hostelworld users have told us that "the staff are definitely the best part" of this highly rated hostel; one guest described the staff are "friendly, enthusiastic, warm, easy-to-chat-with, adaptive [and] cool". This hostel is also ideal for budget travellers looking to make friends, as they serve a free communal dinner every night.
