Apartment was really cute and clean (and it includes AC which was fantastic as it was 36 degrees in Madrid during our stay). It had everything we needed, and is located just off the street with lots of shops and restaurants, including a supermarket that's open 24 hours a day. A bottle of wine from the host was a really nice touch! We also had the car which we didn't use much in Madrid since our plans have changed, the paid parking is just 5 min walk from the apartment but it wasn't cheap - 36 euro per day.
Overall, I would recommend this apartment for your stay in Madrid!
