What a location! Minutes away from Plaza del Sol and seconds away from Plaza Mayor, staying here put us in the middle of old city Madrid action. Soraya met us at the flat and showed us around. She let us know that if we needed anything, we could email her; but we never needed to. The flat was lovely, bright, and clean.
Because the flat is in the middle of all the action, we would recommend ear plugs for late night and early morning (Madrid never fully sleeps). We would definitely stay here again should we be blessed to return to Madrid.
