A great apartment in a superb location - literally around the corner from Plaza Mayor and Mercado de San Miguel - and absolutely brilliant value for money. We stayed in January and the apartment was easy to keep warm, there is a fully functioning kitchen and the bathroom was clean (though no shower curtain during our stay, which was the only issue). Maria was very attentive via email and gave us many tips for sightseeing. All in all this was a great base from which to explore the sights and sounds of Madrid.
