We had just one night here in what turned out to be marvellous, if cold, weather.
Our ger was basic but warm and comfortable. Beds were adequate and a towel provided. The ger had electric light and a wood fire which burnt down quite fast so there was a need to get up to enliven it in the middle of the night. A vaccum of hot water was provided.
The admin block contained shared toilets and showers with separate provision for men and women. The dining room was there too. We had full board. Breakfast was good, lunch was a good, filling hostel type meal, dinner was fine but a bit thin. We didn't have much to do with staff but they seemed friendly and helpful.
The park is good (small exhibition on site) and we were able to get easy, safe, walking in on our own from the camp.
If you get all precious when there is no hairdrier, TV or other frippery this place is not for you. However if you want to spend a night on the steppe in traditional accommodation (and if you don't why are you in Mongolia?) then go for it!
