Here's the story: limiting a trip to two weeks, even for budget reasons, isn't always the right calculation, especially in low season. The main character, a student broke like me, knows that sometimes, staying longer can reduce the daily cost. Imagine: after the first two weeks, we've identified good addresses and local tips; we can even negotiate a lower rent for the third week, like when looking for a studio for an internship and the landlord is more open to a longer stay. So, the budget also involves playing with the duration to lower the final bill.
