Looking for an inexpensive vacation rental for one week

I will be going to Rincon with my wife, our 22 year old son and our 21 year old daughter.  We want to stay from 1/21/2014 to 1/28/2014.  The dates may be flexible.

Does anyone know of a very reasonable vacation rental?  Do you know someone else you can refer me to who may be able to help us out?

I will also be reaching out to some folks we met the last time we were there for help but every little bit helps.

thanks in advance,
Art Vance

I would check out the airbnb site and vrbo. These are typically the more affordable than hotels.

Probably too late but Homeaway.com has many vacation rentals.  I have a house in Isabela that I rent out.
