I would totally recommend Inta's flat. It's brand new, very clean and very quiet, with everything you may need (hairdryer, hot water, bath gel, high-speed internet, etc.). It's not very central, but such a bargain... you can afford to buy a 24h bus ticket and move around quite easily and quickly... I stayed here after missing a flight, and Sergei was very quick and helpful in preparing the flat for me at very short notice (6p.m. for the same night!), and in giving me instructions on how to get to the place by public transport, and even assisting me in finding some unusual souvenirs to take home... Thanks for everything!
