The pros: The location is amazing, in the Salamanca neighborhood and right off the beautiful Retiro park. The building is nice, and the apartment is well equipped. Most of all, the terrace is truly amazing.
The cons: We were on our honeymoon and so excited to stay in the place that was advertised. For the most part, nothing is the listing is untrue. The apartment is just badly in need of upkeep. The cover on the terrace is broken. The mattress sags in the middle. There is significant cosmetic damage to walls, door frames, light fixtures, and showers. The AC in the master bedroom was broken and buzzing all night. The hot water was out. The dryer didn't work. Dan responded to our messages but wasn't able to remedy the issues during our stay.
With a few days of maintenance, this could be an amazing place for your Madrid stay. But for our honeymoon, in its current state, the apartment was disappointing, especially since AirBnB endorsed it.
**Note- based on his response past reviews, I expect the owner to write that I'm lying. I'll just add that AirBNB did refund some of our money and I'd happy to back up my review with pictures if I were allowed.
