I had a really great stay! The house was clean and modern! It was located 3 minutes away from the metro station and it was very easy to reach from the airport! The hosts were also very nice and friendly! Another very good thing was the heating which can be a problem in many places in Spain! The only thing is that the walking distance to IFEMA is around 40 minutes by walking which you might wanna consider in case you visit Madrid for an event at IFEMA.
