We would recommend the Dadhikar fort hotel. It is off the beaten track, with amazing views of the surrounding countryside. The facilities are fairly basic , but the rooms are clean and the staff friendly and helpful. The food in the restaurant is very good but generally only one option ie vegetarian Thali or buffet in the evening..
Some of the rooms have amazing private terraces and so would recommend asking for Himgiri ( all rooms named). This has a large terrace, decent shower and benefits from being next to reception to access WiFi ( only available in the reception area).
Also to note : I am not sure if you can make card payments at the hotel.
The Sariska Tiger Reserve is about an hours drive away.
