Have stayed at Lumen a number of times. The hotel has been recently renovated. Kudos to Kimpton for adding a very cool vibe, nice pool, great restaurant (I believe it is independently owned), and trying to create a great small hotel. Location remains outstanding. Close enough to downtown and to Greenville Avenue to enjoy, right next to SMU, and sitting in the midst of Dallas' high-end neighborhood Highland Park. Unfortunately, the hotel is noisy. Many rooms have a view of a cinder block wall, thus resulting in a dark room. Additionally, the shower is located in most rooms facing the bedroom. I guess if you are alone it is ok, but when traveling with anyone else it is just plain strange. Overall I am going to give the Lumen an "A" for effort and a "C" for results.
