1980's internet experience
There are several things to not like about this Doubletree. I travel to San Diego weekly and my company continues to put me up at the Doubletree downtown. 
First and foremost is the lack of internet connection in your room. They say that there is both Ethernet and wireless. When you call the front desk because you are SO frustrated at NOT getting on, they tell you that there actually is NO Ethernet, only wireless. When you sign on to the wireless, it's slower that the old dial up, (if any of you remember that). I called the front desk again and said that all the hotel guests must be online right now, so that's why the slow internet. It was 2AM. Ridiculous.
Secondly, the water in the bathroom water smells like raw sewage. I have no idea why. I ended up brushing my teeth with my bottled water.
Thirdly, the plumbing pipes rattle in the middle of the night so loud that they wake you.
Lastly, the rooms are musty and old.
Let me just say that I am NOT one of those people that write bad reviews just to spite hotels that I don't like. I truly hope that someone at Doubletree will look at this and decide to make a change.
