I travelled to Madrid with my parents and aunt and we had an amazing experience at Alicia's and Carlos' apartment. Alicia was extremely nice and very helpful when we got there, and she was very punctual for our check-in. And the apartment was perfect. The location was ideal as we were able to walk to every tourist spot in Madrid and the apartment was fully equipped and very comfortable, exactly like in the pictures. Besides, there are a lot of good restaurants, markets, and shops within a shot walk. I definitely recommend staying there.
