If you’re looking for the polished, air-conditioned artifice of a downtown boutique hotel, do yourself a favor and stop reading now. Mellow Hostel isn’t that. It’s located in Horta-Guinardó, a neighborhood that requires you to actually use your legs. It’s a place where the tourists are outnumbered by old men carrying grocery bags and the sound of scooters echoing off steep, narrow streets. This is the real Barcelona, the one that doesn't care if you've had a long flight.
Arriving here is a physical act. You’ll likely step off the V17 bus or emerge from the Vilapicina metro station and realize that the map didn't properly convey the verticality of this city. By the time you reach Carrer d'Aguilar, your quads will be burning and you’ll be questioning your life choices. But then you step inside, and the vibe shifts. It’s called 'Mellow' for a reason. There’s a communal kitchen that smells of cheap pasta and ambition, and a staff that generally operates on 'island time,' even if the island is a hilly suburb of a Mediterranean metropolis.
The rooms are exactly what you’d expect for the price: basic, functional, and devoid of ego. You’re here for a bed and a locker, not a pillow menu. The review highlights mention the showers and the sheets—listen, it’s a hostel. It’s clean enough, but you aren't here to spend your day staring at the walls of an eight-bed dorm. You’re here for the rooftop. That terrace is the hostel’s saving grace, a sprawling space where you can grab a cheap beer, watch the sun dip behind the Tibidabo mountain, and realize that being away from the center has its perks. You can actually breathe up here.
The big draw, the reason people trek this far north, is the proximity to the Bunkers del Carmel. It’s a twenty-minute hike from the front door, and it offers the best view of Barcelona, bar none. While the crowds at Park Güell are fighting over selfie spots, you can sit on the edge of a Spanish Civil War anti-aircraft fortification and watch the Sagrada Família glow in the distance. It’s visceral, it’s beautiful, and it’s free.
Let’s be honest about the flaws, because the 3/5 rating doesn't lie. The stairs are a bitch. If you have heavy luggage or a hatred for inclines, you will suffer. The service can be indifferent, and the distance from the Gothic Quarter means you aren't stumbling home from a club at 4:00 AM unless you’re prepared to pay for a long taxi ride. The 'eco-friendly' tag means they take recycling and energy consumption seriously, which is great, but don't expect the lights to be blazing 24/7 or the water to be scalding for an hour-long shower.
This is a place for the traveler who wants to see how the city actually functions when it isn't performing for visitors. It’s for the backpacker who values a view and a quiet night over being in the middle of the tourist circus. If you can handle the hike and the no-frills reality of hostel life, Mellow offers a perspective of Barcelona that most people miss because they’re too busy looking for a Starbucks near Plaça de Catalunya.

Massive rooftop terrace with panoramic views of the city and Tibidabo
Located in a quiet, authentic residential neighborhood away from tourist traps
Eco-friendly philosophy focusing on sustainability and renewable energy
Carrer d'Aguilar, 54
Municipality of Horta-Guinardó, Barcelona
A spinning, neon-lit relic of neighborhood childhood, tucked away in the dusty, unvarnished heart of Horta-Guinardó, far from the Gaudi-crazed tourist herds.
Escape the sweltering, tourist-choked streets for the open Mediterranean, where the city skyline bleeds into the dusk and the Cava actually tastes like freedom.

Barcelona’s oldest garden is a neoclassical middle finger to the city’s chaos, featuring a cypress maze where you can actually lose yourself—and the crowds—for a few euros.
It is worth it if you are on a strict budget and prefer a quiet, residential atmosphere over the chaos of the city center. However, be prepared for a lot of walking and uphill climbs.
It takes about 30-40 minutes to reach the center via the V17 bus or the L5 metro line. It is located in the northern Horta-Guinardó district, far from the main tourist hubs.
Yes, it is about a 15-20 minute walk uphill. It's one of the main advantages of staying here, as you can easily catch the sunset without dealing with long commutes.
Yes, they offer both shared dormitories (ranging from 4 to 10 beds) and private double rooms for those who want a bit more privacy.
