    Everything is actually pretty good for me. If you’re looking for a cheap and close to the center, this is the hostel for you. Nothing fancy about the breakfast but the cleanliness and facilities is 👍🏻. Make sure to have a 🔐 with you for your lockers. Staffs are very helpful too. I’d go back here.

    Location is perfect. Metro is close, and youre right by the Gran via and all the museums. Locers provided, but no one seema to use them. Showers always have hot water. Gold for the price. Barely slept, but that was my roommates fault not he hostel's.

    Pros- Clean, nice staff, small kitchen and on site vending machine for snacks, bunk bed was quite comfortable, rooms were quiet. Free Carry-on size lockers for your stuff in the hall (bring a small lock). Option to rent hotel style lock boxes right beside staff computer in case you have lots of cash or a laptop. Cons- Smelled a bit too much like cleaning product, not much of a common area. Overall it’s good value.

    Basic. The location is not far from the very centre, and also very close to a metro station, and it's quiet. But It took me a while to find it since it's a bit hidden. The place is clean but small and basic. The room was a bit crowded. There are lookers in the room. They don't make the bed, just gave me the bed sheets and I needed to make it by myself. Towel is for rent for 2 euros. The breakfast is extremely basic, I couldn't find anything to eat there. The stuff were useful.

    Overall the hostel was comfortable, however I do have critique points. Minor: - One member of staff was unpleasantly sexist (the rest were really nice, though!). - The toilets were unisex so, us ladies, had to use toilets covered in pee. Major: - There were bed bugs/fleas in the bed. I left the hostel covered in bites that itched awfully. Luckily I didn't bring the insects back home but still I'd advise against staying in the dorm until that is sorted out.

    Good: Easy location to Metro near main sights. walked to hostel in 7 min. Israel was super helpful, speaks English & Spanish fluently. Free breakfast juice.bread.jam.cereal.muffins. Lockers outside room. Bad: Horrible staff Marienella. I was friendly, spoke Spanish, she didn’t say hi back, stared at me nasty. Slammed clean dishes away in front of me tho there was still 30 min left of breakfast, tossed bread in my space, flung open cabinet doors & hit my toe, never said excuse me, mopped my toe.
