The third modern hostel to have newly opened in the centre recently, Sweet stands out for its good top floor views of the city. As we've come to expect from good hostels these days, the furniture and decor is very modern, there's free internet access and a fully fitted kitchen for guests. Housed conversely in an adapted apartment, be ready to find this place without signposting of any description. Look for 'sweet hostel' amongst 20 or so bona fide Serbian names on the doorbell panel.
