First off, I love Kimpton hotels. Lumen is another fun, boutique type hotel. It had a very reasonable rate and friendly staff. It loses a star because while it is on SMU's campus there is nothing around it worth walking to. Also, the shower is great, but it is completely exposed so if you are staying with a friend or kids, there is no privacy. I was lame, so it was fine.
The bed was very comfortable and I had a great night's sleep. Very reasonable, comfortable stay.
