First time hostel traveler and it wasn't a bad experience, just a few irritating things.
Staff was really friendly.
Bathroom area could be better; the shower wasn't that great and kind of a hazard since I almost slipped and killed myself on the small mat that was outside the shower and you had to mop up after yourself because water leaked out. Its not a huge deal but it could be better and remember to bring a towel.
Breakfast was alright, nothing special.
Daily cleanings which is nice.
card activated lockers so you can keep your valuables safe.
Walkable to a metro station and pretty close to Gran Via area.
Relatively quiet and people were respectful. I did get a little warm in my bunk when I closed the curtain so maybe bring a small fall with you if you get warm at night.
Also, someone stole my sneakers. Like, they were just Fila sneakers, nothing expensive but it was like, really? And there is an assumption about check out times, not good to assume so I was late and didn't even realize it but the staff but nice enough about it so I could gather my things and get myself checked out. It wasn't on my email, so for future reference, check out is at 11am.
I'd stay again, but will be more careful about my shoes.
