My friend and I stayed at the Knezevic Guest House for one night in August 2011 after visiting Plitvice Lakes. We had a very nice twin room with en suite bathroom. Overall, we both thought that the guest house was great value for money. There were certainly 'no frills', but this was fine as we used the guest house as a place to rest our tired bodies after a day of walking around the Lakes. In terms of it's location, Knezevic is about a 10 min walk from the entrance to the national park (make sure you ask the owner for the short cut directions!), which is just stunning.
We didn't have breakfast at Knezevic as we had previously been advised that it was npot worth the extra 5 euros charged. Having said this, I saw the breakfast being served in the dining room and it did look very nice.
Overall, we would recommend Knezevic guest house for any one who is looking for a basic, but clean and friendly, place to lay their head after a day of trekking around the Plitvice lakes.
