Perfect stay. No issues at all. The apartment is clean, quiet and spacious. The roof terrace is lovely and suprisingly secluded. Communication with Mercedes was easy - at no point was I concerned or unsure about anything. The apartment is in a very elegant, vibrant area with a wide range of bars, restaurants, cafes and shops on the doorstep. One thing to note - the apartment is at the top of the building and there's no lift, so be prepared for some exercise. All in all a perfect base for exploring Madrid. Will definitely book this apartment next time I visit.
