Me and a friend stayed at Fernando's flat from Thursday to Sunday and it was a very fine place to stay for our visit to Madrid. Fernando is very hospitable and flexible. He prepares a different breakfast each morning at the time you agree and stayed up when our late arrivalflight was delayed further.
Planning the trip Fernando forwarded a guide on how to get from the airport to his flat, the same also for the return trip.
WiFi is free and works perfectly.
Thank you for the stay Fernando
