This hostel is all aboat the location, which is excellent! A few minutes walk from Puerta del Sol, Plaza Mayor and other central spots, as well as the metro stop Opera very close by. The cheap price than, as expected, is due to a very basic, but functional standard. The rooms are small but have all the essentials, no view to talk about, but clean and with fully equiped modern bathroom included in the price. And who is in Madrid to hang about in hotel room anyway? It is tucked away in a small sidestreet (more silent for sleeping) and may be hard to find as there is no large sign indicating the name. Instead, you see the name tag as you would for someone's flat next to the door. The hostel is one stair up, good since the elevator is very small... Friendly staff, could print my next reservation free of charge. All in all I recommend the place, but be prepared that it is the location that is the main selling-point.
