Graet place, great host. Centrally located, in one of Madrid´s chicest areas. Minutes to the metro, and the place has everything you need on your doorstep, including 2 gyms for which you can pay by the day, spermarket, cafes...
Fernando is vey welcoming and helpful, though as a busy professional you have space to yourself too. Would highly recommend this place for weekend stays or longer business or professionals stints.
