"Younger travelers will be glad to know there’s a cool, affordable hostel in Madrid. Generator has a solid location—just off Gran Vía—and plenty of swagger. Solo travelers can share two-, four-, or eight-person rooms with bunk beds. All rooms have hardwood floors and exposed metal accents; double rooms have cushioned headboards and funky design details. Unlike a full-service hotel, some showers are located in hallways; like a full-service hotel, though, there are power and USB ports—and you don't need to pay extra for sheets. There's a lively bar scene (and great views) up on the rooftop terrace. Generator is worth it for the price—and the potential to make new friends. Save your euros for an amazing meal or cool tour."
