We stayed here when we went down in November.

Our price was around $70/night but now its showing closer to $120. They were renovating when we were there so maybe they are done now or something. Anyways, the price was right, included internet and breakfast, was right beside a 7-11 and close enough to the freeway that we were able to get anywhere pretty quick.
