This is thee best place to stay at in Zagreb the hostel are run by a family, who are the coolest and most nicest, helpful people in the world. They serve cheap and good tasting, local beer for 7 kuna(the currency in Croatia, it's under a eruo) water, and a couple of toasts. A night costs about 90-100 kuna and contains much for the cheap money. a bed, a nice, clean bathroom, 1 free beer, helpful staff, luggage room. lockable lockers with room for a BIG backpacking rugsack. The hostel are a bit far walking from the trainstation, less from the bus station. but trams stops literally just outside the door. Not to mention all the nice people who stays there! You'll definitively get new friends from all over the world^^

And BTW, I can't completely remember if the hostel are spelled LIKA or LINKA, sorry ehe...
