Youth Hostel where Any Adult Can Stay
Easy in-&-out, 8 beds (4 bunks) in a room doesn't bother me - I could have put a lock on the in-room locker, and could rely on front desk to secure my stuff (in a City with high theft rate). Internet worked, and it was comfortable to hang out on couches in the lobby, so roommates weren't disturbed.
Single toilet/sink/shower room for 8 beds meant roulette, trip to lobby with 2 toilets (4 flights below) or wait - no alternative to waiting for shower.
A stay at Ideal Youth Hostel places you in the heart of Barcelona, steps from La Rambla and Palau Guell. Featured amenities include dry cleaning/laundry services, a 24-hour front desk, and luggage storage.
