Traveller reviews
Muhammad Saad “It’s worth to stay in Onefam really loved it”
27 Oct 2025
Everything is super organised and love the small activities they does really enjoyed my stay
Pedro “Incredible place to stay and it gets better and better the more days you stay.”
27 Oct 2025
I would start by saying that the best thing of the whole experience was the staff. The volunteers went above and beyond in helping me out and making me feel like I was at home. Special shoutout to Bel, Lucas and Angel at the reception for doing a great job and being able to talk and help whenever I needed. Corporations love to say we want you to feel like you are at home or we are family, but onefam does make you feel that way. The place had everything you would expect from a hostel. And they might advertise as a party hostel but you won't hear any noise after 10 pm which is great even if you go for work. The family dinner is free and it is really good. You get a kitchen full of utensils for anything you need and there is even some free stuff in case you need pasta or oatmeal. I met people from all walks of life and some of them even returned to the hostel just because they loved the vibe and the people.
