Excellent location, but a bit hard to spot with no signage. Look for the #6 above a dingey door. Inside it’s immaculate and modern though so don’t worry. Didn’t enjoy the lack of sound insulation or having to leave my room to go toilet, but otherwise everything was pretty great for a hostel price. There’s also a huge jar of free ear plugs by the front door haha. Staff were super nice and readily available. Easy to store luggage after checkout etc. And a decent little brekky/coffee joint right across the alleyway that’s open relatively early. When you head away from Ramblas (turn right out the door) you’re about 5 mins walk from CCCB and MACBA. Also recommend a great restaurant around the corner (first left in same direction) called Rao (dinner only). The Pablo blanco cocktail is superb😘🥂
