I visit Madrid for work multiple times a year, and Diego's place was probably the best place I have ever stayed. The location is perfect, central, safe, and right next to an entrance to a metro station. The inside as gorgeous as anything in a design magazine; the decor is immaculately curated and the pictures don't even fully do it justice. The wifi worked perfectly, the temperature was great, the shower felt luxurious and everything was very comfortable. Diego was very accommodating for me, even when I had a very late arrival past midnight. Diego was welcoming, friendly, responsive, and gracious. I was very grateful for such a lovely stay!
