I'm a 22 year old female. I have an internship this summer in Salamanca and I'm looking for any type of an affordable place.

I'm looking for my own bedroom with a comfortable bed and lots of light, in a decent location and an affordable price. I want to pay less than $500 USD (preferably USD$300+) and I would prefer living near Salamanca. I would love if there were a pool available but I don't want to ask too much. I don't know the specific dates of when I will be there, but I'm hoping the beginning of June till mid August, so a little more than 2 months.
