The flat was absolutely lovely! There was 2 of us staying and it was the perfect space. Javier left lots of ammenities (towels, extra bedding, plenty of plates, glasses, shower gel, cleaning equipment, etc). There was air conditioning and wi-fi provided as well, and there awas lots of wardrobe space. Plently of equipment if you want to make dinner as well as there are lots of markets for food around the area.
We didn't know much Spanish but he still helped us a lot with checking in. The location is so perfect as it is right in the centre of Madrid; there are plenty of restaurants, cafes and shops around the area as well.
