You can't beat the location. It is right on Gran Via in the center of it all. The unit is a bit dates and "intimate" but for the couple of days we spent there it was just fine. The host (and management company rep) were very responsive to all our questions and met us at the unit at the agreed upon time. The unit has two bedrooms that can comfortably fit up to 4 adults. Small living, kitchen/dining space but you don't really need it when visiting Madrid since you'll be out all day exploring and eating at the amazing places the city has to offer.
