The Hat Madrid is a hostel that caters to smart travelers, located in Plaza Mayor, Madrid. It offers a variety of amenities, including a rooftop terrace, a bar, and a social kitchen.
I had a short stay here during my stopover in Madrid as I was making my way to Portugal as a solo traveler. I stayed in a shared room with a private bathroom with no problems. The Hat Madrid is in an excellent location that's easy to walk, has a great atmosphere and the rooftop bar is definitely a major highlight!
