Best location you can ask for! It is literally in the heart of Madrid and everything we wanted to see was in walking distance except the stadium, which was no problem since the metro is yards away from the place. We were also able to enjoy the night life and could walk back to the place early in the morning. Ariel was an amazing host and extremely helpful. He was very accommodating even when we checked in after a close to midnight flight. Responsive to questions before hand and can give good tips on where to go in Madrid. The Internet was a little spotty only when we were trying to Skype but he was even nice enough to move the router for us since i had an important Skype session during the stay. The place itself was very clean- so was the bathroom. Highly recommend booking Ariel's place- you won't regret it. It made our Madrid stay one of our favorites! Unbeatable location and great host!
