Helen and Martín are hosts par excellence. Their property is cozy, clean, and centrally located in Madrid, and they communicated with us regularly throughout our stay. They went out of their way to arrange smooth, friendly check-in procedures for us and made the whole process of re-starting international travel after over a year going without it as comfortable as possible. I could not recommend being hosted by Helen and Martín more highly and am grateful for their warmth and attentiveness throughout our stay!
