Mercedes is one of the best hosts i ever meet on AirBnB. Her place is absolutely beautiful and you can find all you need at there. Not only the place is conveniently located between 2 metro stations ( 10min walk from Atocha Renfe and 5min walk from Mendez Alvaro), the stunning window view from my room has left a good memory for my trip in Madrid. Mercedes herself is lovely and helpful. It's a truly pleasant stay here and pleasure to meet with her too!
