As always money makes an appereance, if there's no money, 
If you wonder where to stay, Peru offers all types of places, from the most expensive to the cheapest. A comfortable double room could cost from $20 - $40.US dollars, theres also, camping which is usually free, but then safety may be a concern.
people like you that wonders about what is like to travel to Peru cannot dream about even going there. But, don't worries there are always thousands of possibilities that can help to accomplish it. The first thing to know is the new sol (S/.) Spanish for sun, is Peru's new currency and it is worth 3 times of a dollar. Supposedly, one can eat with $3.US dollars, but it all comes down to what kind of food you are looking forward to try once your are down there. Dollars and soles can be used easily everywhere. Every place I went to in Peru accepted dollars, but if you are like me that likes to get in touch with the regional currency, you better exchange some money before going anywhere. Cambistas, as they are called in Peru, exchange euros and dollars on every corner of the city, commercial or tourist centers, and offer the best rates of all places.

Another thing to realize is that, costs vary a lot according to Peru's weather seasons. The relation is the best weather higher prices which usually go up about 20- 30 percent. One thing to remember to bring along is some sort of student card. Places like museums and tourist spots among many other places, offer discounted fees to local and international students. I had to pay exhorbitant amounts of money just because I didn't think about that little detail (tourism + student= lower fees) Keep that in mind.
