Absolutely stunning apartment in an amazing location. I was in Madrid with 3 friends to celebrate my birthday and staying here made it extra special. Unfortunately Marion and Arthur were out of town so I didn't get to meet them but communication from them ahead of our stay was very good and the check in and out by their friend Vivien was very smooth and easy. Such a modern, clean and well equipped apartment. The wifi and sound system were fantastic and the terrace incredible - the whole apartment is so impressive and I would definitely love to stay here again if ever back in Madrid. Best place I've stayed in yet, highly recommended!
