with 11000 soles you would have 1830 soles per month. That money is "extra"? That is, what is your budget away from the registration? If so, then you have enough money to live. Here are rooms for students for a very cheap price and and also, they have their own cafeteria where you can feed at a low price. Mobility is not as expensive. But you will spend much money at parties HAHAHA Where will you do your interchange?
