Decided to use the shuttle service as I arrived late at night and was aware the apartment might be hard to find. Was met by my friendly host Davor, who showed me where the apartment is in relation to the main square - literally 30 seconds walk! Great thing is that, as busy as the square is, the apartment is on a quiet side-street with no noisy bars/cafes to disturb the peace.
Apartment itself (#1) is on the first floor, roomy, with high ceiling and nice furnishings. Bathroom is a bit small but well cleaned and with a decent shower. A small balcony was a bonus, as was the tea/coffee facilities.
Before leaving, Davor provided some restaurant recommendations and, having tried a couple of them, he was spot on!
