Hi Dustin, sorry for the super late response. You are probably here by now and have learned all about renting and such but maybe this will help for future visitors.
Be careful, Candela is a friend of mine and her situation is rather unique in that she got a great deal on a rental from a friend (sort of a sublet with no contract).
THIS IS RARE!!!
Normally you will need to sign a contract and, if not a year, 6 months will be the min. if you want your own place.
Paying 1st months (or first 2) plus 1 month security deposit is normal here.
If you want to have the flexibility to move in and out easily, you would be better off renting rooms in shared flats instead of getting your own place which will require a min. contract.
