We stayed here for three night with my wife. Good value place situated in the heart of Madrid city center. Marco was very responsive et helpful. Although the place was on the 3th floor you’d still receive noise from the crowded plaza de santa ana. However, you won’t get bothered if you’re a late sleeping person and you might want to try and enjoy in place. Check-out is at 11am and not flexible. Still, you would have the option of leaving your luggage at Marco’s offices if needed.
Very recommandable place and we are definitely coming back once in Madrid.
