Just adding an update to this thread. I am staying at the aLoft this week in Dallas and I really enjoy the experience. The rooms appear to all be a little bit different from each other because of the way the old warehouse was converted. Lots of exposed brick walls in my room and a long bay-like window from wall to wall.
The staff has been particularly accommodating and remembered me by name after a short introduction at check-in. I highly recommend this hotel if you are coming to the Dallas area, I will certainly be back.
