Wonderful experience. Alessandro's flat is breathtaking and it is nearly impossible not to feel home as soon as you pass the door. Great spaces, everything was clean and tidy. It is also located in the perfect area if you want to taste the authentic side of Madrid : La Latina is the essence of the town, two streets away from Plaza Mayor.
I don't really have negative details to share, actually. Alessandro himself is a friendly and lovely person and knows how to give you a quality welcome.
Highly recommended !
