Apartment was terrible choise for a family, extremely noisy all day. Either renovations door bells ringing 3-4 am or people moaning during intercourse. The location is nice though but the owner didn't inform us about the conditions although he knew that it was a family trip, also he booked transportation for us with no additional cost according to him (but eventually it was 10 euro more expensive than normal airport taxi)to his office(not the apartment) and had to walk with all baggage and baby to the apartment.
The outrageous part is he had me signed an agreement that I'm not gonna make any noise or party in the house but obviously was the only person in the complex that agreed.
Overall the location is great if you want to walk around madrid but all the else is terrible plus a greedy lier host.
Personally I'm gonna avoid this host in my next visit to madrid.
