We’ve just spent 4 nights at this Airbnb. The positives are it’s suuuuper close to the centre - 2 min walk to sol station in one direction and the Plaza Mayor in the other direction. It was also well equipped and had everything required for a short stay including a tv with Netflix, Spotify etc. The shower was great and there were fresh towels and AC.
The negatives are unfortunately when we stayed there was work going on in the building between 9.00-18.00 every day so there was lots of loud banging and electric drills. Unfortunately the hosts had no knowledge about this so it seems the neighbours did not inform them. Also, one of the beds had make up stains on it and hair on the pillows so it seemed like it wasn’t cleaned - however the hosts said a cleaner came in between guests so not sure how that happened.
There is also a small window at the top of the bathroom into the bedroom which meant that if anyone goes to the bathroom during the night, you may get woken up by the light.
Overall we had a pleasant stay though and loved Madrid!
