Fantastic location. You can literally walk to all the major spots. Super convenient since there in an elevator and a carrefour right in front. A minute walk to Gran Via station. It is actually really cool in the room even though it is super hot in Madrid. He was really friendly and explained everything clearly. The whole place was nice and clean. Ariel also let us leave our luggage since we came back from Toledo in the evening. He replied very fast to my messages, and he is a wonderful host :)
