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. Onefam is a hostel primarily for adults and may not be suitable for minors. Guests under 16 must be accompanied by a legal guardian. Guests aged 16–17 require prior parental authorisation by email.

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 and nighttime adventures, and share our expert knowledge of the city.

If you still need more convincing, Onefam Sants is tucked away in one of Barcelona's coolest local neighborhoods, where you can experience the city's authentic atmosphere. Right on our doorstep you will find a charming food market, traditional shops, and classic bars perfect for eating and drinking like a local. The main sights of Barcelona are all only a few metro stops away, we are very close to Camp Nou (Barcelona's famous football stadium), and near Montjuïc (Barcelona's largest park). Also, Sants train station is only a short walk away.


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

I was satisfied with everything except heating. Our dorm was right above reception and the walls were paper-thin, some doors were creaking... we heard a lot even through earplugs. Staff was pleasant as always with OneFam, we attended free vegetarian dinner and that one was pretty cool too. The common room was locked, but you can still use the one right at the reception.

As a female solo traveler, this was my first time staying in a hostel and I'm so glad I stayed at OneFam. Everyone was so welcoming and respectful. The space was clean and bed was comfortable. I want to shoutout the amazing staff as well: Manon made my stay so amazing! She helped me get settled and oriented and was so kind! Angel, Rick, and Kelsey were also very welcoming. I would stay here again, thank you!

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.
