The apartment is nice and cosy, and overall comfortable. The location is perfect as it is in the very center of the city : you can go anywhere by foot (we almost never took the subway or the taxi during our stay). Alberto is very responsive and able to answer all questions, and he let us leave our luggage a bit longer as our flight was taking off in the evening, which was very much appreciated. I do recommend to stay there for a trip in Madrid : very good value for money !
