We had a wondeful stay at the apartment. The location is great: you can walk to every place of interest. For your breakfast in the apartment there is a Lidl right around the corner. The only thing we did not find was the yacuzzi as described at the site!
Ida was very helpful and answered very quickly. The description how to reach the apartment was outstanding: a video and a metro-map. I recommend the apartment for a stay in Madrid.
