The Aggtelek is on the road from Poland to Balkans, so it's a good spot to stay overnight.
It is on the hill, so a bit diffcult to reach at nicgt, but the owner is very polite and nice man (speaks a little German). He welcomed us even late at night with dinner and some drinks (3Eur/person).
The showers, beds, towels are all clean and ok and there's plenty of them. Beds and rooms are confortable: clean and warm.
There's a small zoo outside the house with ostriches and sheeps.
Also, near the Aggtelek is a national Park where you can watch birds and nature.
