You are looking for a short term seasonal rental. To the best of my knowledge these types of rentals do not exist in apartment complexes, you need to find a private owner that rents their condo out seasonally. There a many of these types of rentals available through many different websites and as Realtors we have the ability to run a search for you through the MLS system, which is one of the most up to date systems for currently available properties in the area.
Let me know if I can help.
