I would definitely give 5 star to Javier and his very nice wife Carmen and the apartment.
For me, my wife, my nephew and his family including their three year old daughter, the location, size and cleanness was perfect.
Everything was sparkling clean and available on arrival, great location, and walking close to everything including a 24 hour grocery store right downstairs, metro station while all the tourist spots are within walking distance, restaurants( many of them) right around the corner and so on....
I will definitely consider Javier’s apartment next time traveling to Madrid again...
Thank you Javier and Carmen for being such a wonderful hosts...
