With a great location, this friendly hostel is basically one large apartment with a double room and two dorms sleeping six or ten. The dorm room has lockers and wooden bunks, while the private room is cramped, but still fine value for the price. You can mingle with other guests in the kitchen, and play some records in the comfy lounge.
There's also a tiny balcony overlooking buzzing ul Rubinshteyna. Be prepared for chalk stains from the walls!
