We booked a room for one night because we needed an inexpensive hotel in North Dallas. It was a mistake. Not clean, not nice at all. Despite the claim that it was 100% non-smoking, the whole place smelled of smoke and there were cigarette burns on the furniture and bedspread. We asked for another room, and the front desk staff were helpful. The room we got was cleaner, but minimally furnished and with very few amenities (for example, there was a coffee maker, but no coffee cups...). Stained carpet, overflowing trash cans in the halls.
Worst of all, when we arrived on a Saturday night, we saw "working girls" doing business in the parking lot behind the hotel. Fortunately, police arrived and they dispersed. But I would not let my wife walk outside of the hotel alone.
Again, I should emphasize that the staff did what they could to help. We will definitely never go back.
