My brother and I were in Chattanooga for an extended stay looking at real estate, and stayed primarily in The Crash Pad. What a GREAT choice that ended up being. Both the rooms and bunks are well appointed and comfortable, and everything is immaculately clean. The whole hostel is well thought out, and you feel that when you're staying there.
The hostel is staffed by some really great guys. Dan, Jon, Al and Compton were all really knowledgeable and friendly, just solid people really. Our trip benefited from their help and advice tremendously.
The common areas are also really enjoyable. Everything is well designed for a clean and enjoyable guest experience. Blazing fast wifi? Check. Kitchen you would actually want to use? Check. Cool outdoor hangout space? Check. Walking proximity to dozens of cool restaurants, bars and businesses? Check!
In short, you could probably spend an arm and a leg to stay at a really swank hotel for your Chattanooga trip, and your experience would be hard pressed to match the Crash Pad. This is a great choice for anyone passing through town who wants to be right in the heart of the action, to stay in a super clean and modern space, or who wants access to some friendly and good advice about the city and surrounding attractions. Stay there, and you won't regret it.
