Discovery hotel (motel) 1700.00 RUB
28 doubles for 1'700 RUB, big TV, DVD in rooms. Free Wi-Fi zone, restaurant and several types of saunas and "banyas" (800 RUB/h).
Some hotel descriptions claim that it is located in the center. I wouldn't say so - it's about 10 minutes driving by car to the city center without traffic jams and upto 30 with one, not so comfy for travellers w/o car. But still - quite good and cheap option.
Update March 2010:People report, that the hotel do not want to deal with foreigners if they stay for a short period of time.
