Stayed there a couple of times. Rooms are simple pension rooms, cleaniness is about ok, SAT-TV is available mostly German channels - picture quality could be improved - in our room most channels came with a disturbed picture.
The place also has a restaurant where breakfast is served. Continental style breakfast is filling and consists of bread, jam, sausages and cheese, sort an artifical orange juice and a wonderful coffee.
The major plus: the pension has a nice pool open in summer and also free car parking. Without a car you may be better staying closer to the National park as public transport seems to be very limited. By car it's about 10 mins to the north entrance of the park. About the same it's to city of Slunj northbound, where you find a cash dispenser, restaurants, shops etc. Rastoke with small waterfalls in a small canyon is also worth a short visit.
Another downside is noise coming the road outside - with closed windows not a problem, but in summer you may want to open the windows.
Price is reasonable: 42 Euros incl. breakfast. Half-litre Beer is less than 2 Euros, coffee is 1 Euro.

Meals in the restaurant are reasonable priced, however they charge you extra for side dishes.
Food quality seemed to have deteriorated since our last stay two years ago. We had a really bad meat meal - my worst restaurant experience for years. If you stick to the pizza you shouldn't be wrong, with meat dishes you may have to be a little careful. If you're going somewhere else there a lots of other places along the road.

Since I cannot write about the rooms, I can only share my experience with having a confirmed reservation. I booked a triple room for august 23 last year in November. I then confirmed in jan. 2008 and also 1 week before our trip. We had a great day of hiking and then we went to our room. My room was given away, so I would encourage anyone who is arriveing later call and confirm. I didn't have a cell phone, we did stay at a great sobe across the street that I will write a review about it.

We stayed two nights in June and were pleased with the triple, it would be too small for any longer. The place was clean and well priced at 55euro inc breakfast for 3 of us, we booked direct . Its was a bonus to go for a swim and a game of tennis after the plitvice national park! Food in the restaurant is well priced and good and staff were friendly. Given that there are a lot of rooms for rent in the area of the park , we were happy with this choice as we didn't have to get back in the car to go out to eat.

TC-Marko offers very clean, comfortable modern, but basic rooms in a very convenient location to Plitvice National Park at very reasonable rates.
We stayed during the first week of October when the leaves were beginning to change color. The hotel is on the main road out of the park situated on the side of a hill full of apple trees. During the summer there is a great swimming pool.
Breakfast was good with excellent coffee from the espresso machine.
We stayed two nights and ate at the hotel both nights. The food was good, varied, and reasonably priced. What made the dining experience really memorable though was the presence of many local people who were out and live musicians performing in the restaurant.
