Our stay was just perfect! The location of the apartment is just amazing - in the middle of the center of Madrid. The apartment itself is super clean, has everything you need and the organisation and communication with the host Jose María, represented by Minty host, worked perfectly. The only small negative point is that we only got 1 key. Having in mind that the apartment sleeps 8 people, this might be problematic for some.
I would definitely recommend everyone that is looking for a luxurious private stay in the center of Madrid to spend the weekend or even longer to stay here.
