Doubletree in Name Only
I travel constantly for business and rarely take time to write reviews but this hotel is so disappointing for a Doubletree, I feel the need to vent. I've stayed here several times and each time I come away with the same lacklustre impression.
Here's some thoughts:
1) As others have mentioned it is extremely out dated, the carpet and decor are vintage 80s, and not in a good way.
2) Bartender at the lobby bar is the most unfriendly bartender I've ever met.
3) Don't eat the sushi! It was terrible! Edamame was browning and completely disgusting. Nothing seems fresh, very surprised I didn't get sick. 
4) The iron in the room leaked terribly and the ironing board looked like it was 30 years old. Gross.
On the plus side:
1) The rooms are big
2) Room service breakfast was actually pretty good
3) It's close to the airport.
4) The Doubletree cookies are delicious
Overall, I would expect this from a Marriott which tend to be either great or in desperate need of an update. I have always had great luck with other Doubletree properties, they are clean, modern, and comfortable--just not this one. It falls very far short of the mark.
There are lots of options in San Jose--avoid this one!
