I loved staying in Matias' flat. It was spotlessly clean. Check-in and check-out were easy. Matias' fantastic housecleaner Renny met me both times and he really saved me when I left without my computer cord. He grabbed it and ran out to the street to give it to me! Matias communicated clearly and immediately. The flat appeared to be newly renovated with new furnishings and comfy beds. The kitchen has everything guests would need, including a great pod espresso maker, a microwave and everything you'd need if you wanted to cook meals. The location is great too, on a quiet, charming street within a short walk of a metro station and other attractions in central Madrid. I can't recommend this spot more highly.
