My family and I stayed at Enrique and Mercedes' flat in the very centrally located area of Atocha. It was our first time using Airbnb, and our original fears were dissipated by Enrique's prompt responses to my questions as well as his concern regarding our arrival. Enrique helped my wife with her suitcase, gave us local tips, and was overall friendly. I would highly recommend this flat to a group wanting to easily experience Madrid.
