We stayed two nights, October 2012, at the Hilton Garden Inn located just beside he Santa Rosa Airport. The Inn is fairly new and the furnishings are excellent.The hotel is, in my opinion, overpriced. Breakfast is not included in the room rate and the breakfast presented was second to third rate buffet--not the kind of meal you would expect in such an expensive hotel.
The hotel has one serious defect: the roof is metal and water condenses during foggy and dewy nights and the run off drips down into poorly designed downspouts and makes a loud dripping noise that is audible inside the rooms. I spent a sleepless night the first night because of the 2:00 AM--on noise that sounded like a large drippy faucet. The second night the hotel changed rooms to one on the third floor and although I could hear some faint dripping it was much better. I am rating this hotel down, then, because it is not worth the expense, has a second-rate breakfast buffet, and has the awful dripping noise which may make it impossible for people with sensitive ears to sleep.
