Really nice hostel in the old town of Kotor inside a wonderful old building. Nikolas organises free cocktail to welcome the new becomers. He knows all the good addresses of Kotor.
Classic hostel at Podgorica. Good to one night during a transfer (the train and bus stations is so close).
Hostel Majdas is one of two best hostels where I stayed during my trip. The owner is very friendly. She will welcome you warmly, recommend some restaurants, points of view (on the bridge of course), and all the useful places for a backpacker (laundry, cash dispenser, ...).
Peaceful (maybe too much) hostel at Split. Good quality for money rate. Infortunately, no friendly common room (except a too sad kitchen).
