Avoid
I am a platinum spg member and I know my properties pretty well. Please avoid. If you see the spotty reviews, that is a dead giveaway that its not a good property. So if you are a reasonably frequent traveler and have other options. Avoid it.
I lean towards spg properties, and this was close to my place of business in san diego, so despite the spotty reviews I chose to stay here.
The beds are quite uncomfortable. They had people smoking pot in the area, either outside the window (staff or guests?). The food is not good quality - go to a fast food place if you want to. I ordered room service and was disappointed with every course. Staff is quite aloof and un-interested. I know its a four point and not a regular sheraton, but smiles and a professional attitude at the front desk help. I had to resolve some of the issues - by phone and email and it took them 2 months, really two months to respond. 
Spoiled the spg image for me for sure, its back to the hh properties for me in this area.
So if you have other options, go somewhere else.
