The apartment is in a wonderful location a block and a half from the Prado Museum. The area is full of restaurants and you can walk to most of the museums, parks, squares and places you would want to see in Madrid.
The apartment is very comfortable with quality linens and a good pillow (often lacking in such places). It has all the kitchen appliances we needed including a dishwasher and washing machine. We were very comfortable here. Also we arrived early in the morning and were able to leave our suitcases in the apartment before check in time.
