We came from Southern California to Detroit for a vacation -- not kidding. There is much to see and do in Detroit, including the art museum, walks by the river, Renaissance Center, and lots of art deco architecture. The Westin Book Cadillac is a renovation of a historical downtown hotel, and the rooms are completely modern and spacious. Great view of downtown all the way to the Detroit River and the bridge to Canada from our 18th floor corner window (which we got at a discounted rate by calling Westin, not using the website).
Contrary to popular belief, downtown Detroit is safe (probably more than downtown Los Angeles), and we saw many people walking on the streets even late at night. Hotel is not right on the river, but only a short walk away. There are some downtown buildings which are unused (rather than abandoned), but these are charming rather than threatening. We had valet parking and driving downtown was easy.
Rooms and corridors are clean. The employees are very friendly and service oriented. Only exception was the casual dining 24 Grill, where food was pretty good but service was lacking. Roast is their gourmet restaurant, but we didn't eat there. There are other restaurants within a ten minute walk.More
