We had a wonderful stay with two adults and two small children. The apartment is spacious and well designed es and equipped and very comfortable. Particularly the master bed and shower are awesome compared to other Airbnbs we have stayed in across Europe. Everything was clean and tidy.
The location is perfect, walkable to pretty much anywhere, near a metro station, and right across from the San Anton market.
We would absolutely stay here again and highly recommend this apartment to anemone looking for a place to stay in Madrid, particularly with kids!
