Guillermo's place was perfect for us when we stayed for 2 weeks to see Madrid and take an intensive Spanish course. The apartment is close to bars and restaurants but far enough away from the action that it is very quiet. Very close to Checua subway and other subways. Honestly, I'd say it's a perfect location to seeing so much of Madrid. We stayed in March so the ability to use the closed in porch was welcome. The apartment is very sunny especially in the morning. Very much appreciated how well stocked the kitchen is as we did have breakfast and a few lunches dinners at home.
