The Atlantis Dunapark has 79 guest rooms spread over two floors. Getting to the rooms can seem like rather a long journey (some of the corridors are never-ending), but once inside, they are practical and very clean. Most of them offer double accommodation, although some are furnished to sleep up to four guests (two adults and two children, or three adults and one child). The walls are painted white and the floor is covered in light brown tiling. In one corner of the room there is an armchair, and a desk and chair are also provided. The overall appearance of the room is quite harmonious.
The facilities include a flat-screen satellite television, a direct international phone line, individual air-conditioning, a mini-fridge and a safe (for which guests must pay extra). Tea and coffee-making facilities can also be provided upon request (which also comes at an extra cost). The balcony is quite large and wide, and comes with a plastic table and chairs. Features in the bathroom include a bathtub, a toilet, a hair-dryer and hospitality products. A bottle of local red wine is given free of charge to every new guest.
