Very friendly staff that can communicate fluently in English and Spanish. Very full of insightful information about the city if you ask. A very welcoming and quite homely environment with lots of thoughtful little touches. Amazing value for money - everything you need for a comfortable stay, and a great central location. There are reasonable rules for behaviour so it's not noisy at night, and the reception is open 24 hours if you come back late. The hostel isn't very well-marked in real life, so you just need to make sure you find it on Google Maps first, then you need to check the buzzer on the building for the "Youth Hostel," label, and they can let you in.
