High recommended!! Al's place is just as it's written and as you see- Nice facilities, complementaries and location.
(I didn't mind much about staying centro but it turned out it was perfect to walk famous sights in the city. )
I fully enjoyed my 2 nights stay in Madrid. His place is easy to find and Al welcomed me at the apartment. He's friendly, knowledgeable about Madrid's sights. It was nice to know him. If you are keen to hear local's advice, I recommend to stay in his place.
