I stayed there last winter. They have everything you need. For me, the staff A + rest A-
Hotel Slisko was great. The beds were comfy and the cafe had a good coffee. Zagreb was a must-see for us, but we wanted a little luxury but not break the bank. A good little budget hotel.
It was not your ordinary place to stay the night, but that's what I loved about it. A bit of a walk, but also quiet and authentic.
