I don't know about crew hotels, but I stayed at Hotel Dos Castillas (Madrid) in March, and it was great. Classic on the outside, new and modern on the inside, good coffee shop, restaurant and bar by the lobby. Nice rooms, great johns and an unbeatable location near Puerta del Sol and Plaza Mayor. I think I paid about $85USD per night (actually I just checked a last-minute website and rooms are about 70USD right now). That's where I'll be staying the next time I go.
