I stayed here for the weekend with a friend and we loved it. The apartment is very cosy and welcoming with everything you need for a stay in Madrid. There's one bedroom and a sofa bed which opens out into a pretty large double bed that could easily fit two people and the place was spotless clean. The location is amazing, just beside Plaza Mayor. Everywhere we wanted to go was walkable and there are loads of restaurants, cafes and shops on your doorstep. The highlight for us was the rooftop terrace, four flights up, you have a spectacular view of the city, right overlooking Plaza Mayor. There was comfy chairs up there and even plug sockets and a shower. Only thing I would say is that the four flights of stairs are tough to climb, but worth every step when you see the view. Pilar was very responsive and helpful, answered all of our questions and gave us very clear instructions when arriving. Finding the apartment and getting into it was simple. Overall great stay.
