The apartment is great! Very centrally located and EASY walking distance to the major attractions in Madrid. It is a very comfortable space with all the amenities you need for a visit to the city.
Israel was a GREAT host. He was in contact with us a week or so ahead of time to confirm our itinerary and was very accommodating when our flight was delayed. He met us at the apartment at 10:40 pm to let us in, show us around and give us some local tips. He also checked in with us while we were there.
Would stay there again if we are ever back in Madrid.
