help i need a hotel in London!?

iam going on a trip to london at the beginning of next year and ineed to find a hotel,but so far everything i have looked at is wrong. what i need is a hotel within 10-15miles or 16-24 kilometers of big ben. the price has to be between 100.00-200.00USD or 48-97GBP. it does not have to be fancy, i don't need a pool,spa,gym or fancy restaurant. just clean comfortable rooms with there own bathroom and complementary breakfast. if someone could recommend a hotel like this i would very much appreciate it.
