The overall experience was great. I loved Madrid and this also thank to our host and his place.
The place itself is near almost everything and it's very close to the metro station but I preferred to move without it because we also wanted to see the city, not only the monuments and the museum.
The host is worth to be called "superhost": fast check-in, fast in response and always kind.
The house was a bit cold in our period (average 10°C), also with heating on.
