Dobrolubova Street 2
(http://riverpark.ru/?lang=en), formerly known as the ob hotel, on the bank of the ob river, is situated close to the metro just southeast of the city center. after being gutted by fire in the 1990s, it has been refurbished, with reasonably clean rooms, free wi-fi internet, a business center, and a nice russian restaurant on the first floor. don't look for english-language television or air conditioners, but there are plenty of rooms with private bathrooms.

From 1200 rubels for shared toilet/shower
On the street opposite the opera/ballet house.
TV, fridge, and sink in the room. Won't get any cheaper than this for a private room. Grim, shabby Soviet-era accommodations for hardy, budget-conscious travelers. Not recommended for families.
