I've stayed at this hotel for business many, many times over several years. I'm HHonors diamond and therefore frequent Hilton properties all over the country.
The experience at this HGinn is on par with every other I have ever stayed in terms of cleanliness, amenities, etc.
Where they excel is the friendliness of the staff and price. An absolute wonderful group of people. Speaking to price, it's the least expensive HGinn I have ever seen.
Where they fall short is the internet service. I know it's a trivial reason to knock the rating down a bracket, but as a business traveler it's imperative I be able to work from the hotel. You cannot do that at this hotel unless you are in the lobby on wifi. Both the ethernet cable and the wireless internet are worthless in the rooms. I'm certain I've stayed on every floor with the same experience on each over several dozen stays across 2-3 years.
Having many customers from Cartersville to Chattanooga, I used to stay here a lot but shifted my overnights to Chattanooga at a higher price quite honestly mainly due to the lack of functional internet in the rooms. After at least 6 months, I decided to give it another try. No improvements. It's January 22, 2013. i'm in the room right now typing this using my verizon wireless card because both the wireless connection and the ethernet cable will not even open the homepage inside of 3 minutes. Forget accessing email.
If this one area were addressed, this would be one of the best HGinn's anywhere around.
All this being said, if internet is a non-issue for you, you'll have a great experience at a top notch HGinn for a very competitive price.
