This hostel is very neat and clean, looks brand new. The staff is friendly and helpful. The kitchen's got everything you need, tea at any time, that's good.
I missed like a chill out area. I guess when you can stay outside it might be different, but during winter time, there's only the kitchen to hang out, which is not the best for me to relax or to socialize with other travelers.
About the location, the hostel is easy to find, in a quiet street in the center, 5 min walk from the train station which is quite good. I sure prefer the Albaicin area, so this may depend on you.
