Highly recommend this apartment if you arrive with a car. The apartment is located near a free parking lot.
Raquel, the host, was very nice and responded to us kindly and immediately (even at late situations). Also, she also offered help if needed.
We received a very clean and tidy house, and it's truly big enough for larger groups of people (3-5 persons).
However, do notice that the apartment's location is a little far from the Madrid's city center - which is around ~20 minutes using the Metro.
