I was a little hesitant at first because of the reviews that have been posted. But for the price you could not beat the location, as well as for the price you could not be having your own private room in the city center. The shared bathroom wasn’t an issue either because there were multiple bathrooms throughout the Building. I would most definitely stay here anytime I came to Madrid. If quiet sleeping is a must for you I would say that might be your only issue, but I can sleep through almost anything.
