Seriously, If you are a solo traveler or a couple, stop looking. This is your place. Perfect location on a quiet side street that is close to a ton of bars and restaurants and easy walking to many big sites. Dark and silent at night, I slept like a rock which I rarely do when traveling. Totally clean, Great light and air. It seems unlikely that you would want to cook in Madrid but there’s a full kitchen and washing machine which is super handy.
